Abstract:

Osmylation of 2-methylene-5α-androstan-17-one has been shown to afford the 2α-hydroxy-2β-hydroxymethyl derivative whilst 3β-hydroxy-17-methylene-5α-androstane gives the 17α-hydroxy-17β-hydroxymethyl derivative; the facial selectivity of these reactions is discussed.

Abstract:

A range of biological activity was observed for the group of 3,6-anhydro-2-deoxy hexosides, of which 3 is representative, isolated from Sauropus rostratus. Wei-Jia Xie and Xiao-Ming Wu of China Pharmaceutical University prepared (Org. Lett. 2014, 16, 5004) 3 by the dealkylative cyclization of 1 to 2. (+)-Ipomeamarone 6 is a phytoalexin isolated from mold-damaged sweet potatoes. Yoshinosuke Usuki of Osaka City University assembled (Chem. Lett. 2014, 43, 1882) 6 by the diastereoselective cyclization of 4 to 5. Hiromichi Fujioka of Osaka University protected (Org. Lett. 2014, 16, 3680) the enone of 7 by the conjugate addition of triphenylphosphine. Diastereoselective reduction of the other ketone followed by deprotection of the enone and cyclization led to 8, that was hydrogenated to decytospolide A 9. En route to cytospolide P 12, Rajib Kumar Goswami of the Indian Association for the Cultivation of Science had planned (J. Org. Chem. 2014, 79, 7689) the ring-closing metathesis of 10. This failed, but cyclization of the corresponding silyl ether to 11 was successful with the second-generation Hoveyda catalyst. Rongbiao Tong of the Hong Kong University of Science and Technology set (J. Org. Chem. 2014, 79, 6987) the absolute configuration of (+)-didemniserinolipid B 15 by Sharpless asymmetric osmylation of the alkene 13. Oxidative Achmatowicz rearrangement/bicycloketalization then delivered 14. Xuegong She of Lanzhou University observed (Org. Lett. 2014, 16, 4440) remarkable diastereoselectivity in the reductive cyclization of 16 to 17. Oxidation of 17 led to regioselective cyclization to gymnothelignan N 18.

Abstract:

Babak Borhan of Michigan State University found (Angew. Chem. Int. Ed. 2011, 50, 2593) that the ligand developed for asymmetric osmylation worked well for the enantioselective cyclization of 1 to 2. Kyungsoo Oh of IUPUI devised (Org. Lett. 2011, 13, 1306) a Co catalyst for the stereocontrolled addition of 4 to 3 to give 5. Michael J. Krische of the University of Texas Austin prepared (Angew. Chem. Int. Ed. 2011, 50, 3493) 8 by Ir*-mediated oxidation/addition of 7 to 6. Yixin Lu of the National University of Singapore employed (Angew. Chem. Int. Ed. 2011, 50, 1861) an organocatalyst to effect the stereocontrolled addition of 10 to 9. Naoya Kumagai and Masakatsu Shibasaki of the Institute of Microbial Chemistry, Tokyo took advantage (J. Am. Chem. Soc. 2011, 133, 5554) of the soft Lewis basicity of 13 to effect stereocontrolled condensation with 12. Yujiro Hayashi of the Tokyo University of Science found (Angew. Chem. Int. Ed. 2011, 50, 2804, not illustrated) that aqueous chloroacetaldehyde participated well in crossed aldol condensations. Andrew V. Malkov, now at Loughborough University, and Pavel Kocovsky of the University of Glasgow showed (J. Org. Chem. 2011, 76, 4800) that the inexpensive mixed crotyl silane 16 could be added to 15 with high stereocontrol. Shigeki Matsunaga of the University of Tokyo and Professor Shibasaki opened (J. Am. Chem. Soc. 2011, 133, 5791) the meso aziridine 18 with malonate 19 to give 20. Masahiro Terada of Tohoku University effected (Org. Lett. 2011, 13, 2026) the conjugate addition of 22 to 21 with high stereocontrol. Jinxing Ye of the East China University of Science and Technology reported (Angew. Chem. Int. Ed. 2011, 50, 3232, not illustrated) a related conjugate addition. Kian L. Tian of Boston College observed (Org. Lett. 2011, 13, 2686) that the kinetic hydroformylation of 24 set the relative configuration of two stereogenic centers. Alexandre Alexakis and Clément Mazet of the Université de Genève established (Angew. Chem. Int. Ed. 2011, 50, 2354) a tandem one-pot procedure for the addition of 26 to 27 to give 28.

Abstract:

Complex natural products and even some complex pharmaceuticals contain arrays of stereogenic centers. Sometimes, the desired array is readily available from a natural product, but usually, such arrays of multiple stereogenic centers must be assembled. Armando Córdova of Stockholm University has reported (Angew. Chem. Int. Ed. 2007, 46, 778) a simple procedure for the organocatalyst-mediated addition of the nitrene equivalent 2 to an α, β-unsaturated aldehyde to give the protected aziridine 4 in high ee. Organocatalysis was also used (Organic Lett. 2007, 9, 1001) by Arumugam Sudalai of the National Chemical Laboratory, Pune, to effect coupling of the aldehyde 5 with dibenzylazodicarboxylate 6 to give, following the List procedure, the intermediate aldehyde 7. Osmylation of the derived unsaturated ester 8 proceeded with high diastereocontrol, to give 9. Products 4 and 9 have adjacent stereogenic centers. Hisashi Yamamoto of the University of Chicago has introduced (J. Am. Chem. Soc. 2007, 129, 2762) the linchpin reagent acetaldehyde “super”silyl enol ether 11. Diastereoselective addition of 11 to the enantiomerically-pure aldehyde 10, with concomitant silyl transfer, followed by the addition of allyl magnesium bromide delivered the protected triol 12 in high de and ee. Arrays that combine alkylated and oxygenated or aminated centers are also important. Akio Kamimura of Yamaguchi University took (J. Org. Chem. 2007, 72, 3569) a Baylis- Hillman like approach, adding thiophenoxide to t -butyl acrylate in the presence of an enantiomerically-pure aldehyde N-sulfinimine such as 13 to give the adduct 14 with high diastereocontrol. Keiji Maruoka of Kyoto University has designed (Angew. Chem. Int. Ed. 2007, 46, 1738) the chiral amine 17, that catalyzed the condensation of an aldehyde with ethyl glyoxylate 16 with high enantiocontrol. In a very thoughtful approach, Liu-Zhu Gong of the University of Science and Technology of China in Hefei extended (Chem. Commun. 2007, 736) the now-classic aldol condensation of cyclohexanone to 4-substituted cyclohexanones such as 19. The product 21 could be carried in many directions, including to the Bayer-Villiger product 22. Arrays of alkylated and polyalkylated centers have been among the most challenging to prepare.

Abstract:

Hiromitsu Takayama of Chiba University used (Org. Lett. 2014, 16, 5000) the Itsuno-Corey protocol to reduce the enone 1 to the allylic alcohol 2. Peiming Gu of Ningxia University developed (Org. Lett. 2014, 16, 5339) a Cu catalyst that cyclized the prochiral 3 to 4 in high ee. Xiaoming Feng of Sichuan University effected (Org. Lett. 2014, 16, 3938) enantioselective Baeyer–Villiger oxidation of the racemic cyclopentanone 5, converting one enantiomer to the δ-lactone 6. The velocity of catalytic osmylation is often limited by slow turnover of the intermediate osmate ester. Koichi Narasaka, then at the University of Tokyo, showed (Chem. Lett. 1988, 1721) that the efficiency of the transformation was improved by the addition of stoichiometric phenyl boronic acid. Kilian Muñiz, now at ICIQ Tarragona, established (Chem. Eur. J. 2005, 11, 3951) that this acceleration also worked with Sharpless asymmetric dihydroxylation. D. Christopher Braddock of Imperial College London took advantage (Chem. Commun. 2014, 50, 13725) of these observations, converting myrcene 7 selectively to the cyclic boronate 8. Michael P. Doyle of the University of Maryland developed (J. Org. Chem. 2014, 79, 12185) a Rh catalyst for the ene reaction of 9 with 10 to give 11. Adriaan J. Minnaard of the University of Groningen devised (Chem. Eur. J. 2014, 20, 14250) a Cu catalyst that mediated the face selective addition of 13 to 12, establishing the oxygenated quaternary center of 14. Tomonori Misaki and Takashi Sugimura of the University of Hyogo used (Chem. Lett. 2014, 43, 1826) Michael addition of 15 to 16 to construct the oxygenated quaternary center of 17. Jon C. Antilla of the University of South Florida assembled (Chem. Commun. 2014, 50, 14187) the δ-lactone 20 by adding the diene 19 to the α-keto ester 18. Zhiyong Wang of the University of Science and Technology of China reported (Org. Lett. 2014, 16, 3564) related results. Jonathan A. Ellman of Yale University achieved (Angew. Chem. Int. Ed. 2014, 53, 11329) substantial enantioselectivity in the addition of thioacetic acid 22 to the nitroalkene 21 to give 23. Subhash P. Chavan of the National Chemistry Laboratory prepared (Tetrahedron Lett. 2014, 55, 5905) the allylic amine 25 by reduction of the aziridine 24.
