Abstract:
Indole-fused tetracyclic ring systems containing nitrogen atoms are common core skeletons of many indole alkaloids such as sarpagine, macroline, and ajmaline. Efficient and stereoselective construction of these ring systems can promote the development of the corresponding alkaloid syntheses. In this article, we briefly summarize our current progress toward the application of the aza-Achmatowicz reaction and indole nucleophilic addition reaction cascade for the first asymmetric total synthesis of the macroline-type indole alkaloid (–)-Alstofolinine A. Our synthetic strategy is based on furan oxidation/rearrangement and proceeds from easily accessible materials such as indole and furan derivatives.

Abstract:
The second part of the planned review on developments in the field of total and formal total synthesis of the post-secodine indole alkaloids concentrates on modified alkaloid types, i.e. those skeletons derived from primary types by formation of additional and/or rupture of existing bonds, while connectivities next to indol(e)ine moiety remain intact. It thus reviews the synthesis of alkaloids of quebrachamine/cleavamine type including VLB-bis-indoles, rhazinilam type, aspidofractinine/kopsane and kopsifoline type, as well as kopsijasminilam alkaloids, lapidilectine B and danuphylline. It covers the literature of from 1991-1992 up to approximately end 2006. A review with 174 references.

Abstract:
The photocyclization of enaminones was extended to aryl enaminones bearing a substituent on the aromatic moiety. This reaction was studied in order to achieve the synthesis of indole alkaloid synthons. Trials of regioselectivity control were made by using groups with enhanced steric hindrance. The reactivity of secondary enaminones was tested, and the ratio of C-alkylation to N-alkylation was shown to be dependent on the nature of the aromatic substituent. During this work, new hexahydrocarbazolones were synthesized, with substituents on the A ring or the modified C ring. Keywords: photocyclization, aryl enaminones, indole alkaloids, hexahydrocarbazolones-4, cyclopenta[b]indoles.

Abstract:
(+)-Tacamonine, a natural product isolated from the Central African plant Tabernaemontana eglandulosa, belongs to the relatively new tacaman class of pentacyclic monoterpenoid indole alkaloids. Its close structural similarity to the potent cerebral vasodilator (-)-vincamone has promoted several efforts towards its synthesis, culminating in the appearance of two asymmetric and seven racemic syntheses in the literature. This dissertation details the successful execution of our strategy for the concise, highly-efficient, asymmetric total synthesis of (+)-tacamonine. Chapter 1 serves as an introduction to the tacaman class, including the proposed biosynthesis for members of this class, followed by a review of the reported synthetic approaches to tacamonine. Chapter 2 details the evolution of our approach based on the use of key radical cyclization methodology to ultimately accomplish a total synthesis of the target. An investigation of the diastereoselectivity displayed in the radical cyclization step is also described through computational methods. Our route followed a novel ABC to ABCD to ABCDE ring-construction strategy, which first involved the synthesis of 3,4-dihydro--carboline as well as a chiral acid ester fragment that was acquired through Evans’ auxiliary-controlled alkylation chemistry. The latter set the absolute configuration at C-20 bearing the ethyl group in the D-ring, and thereafter, the two fragments were coupled together before being advanced to the radical cyclization precursor. Radical cyclization then led to the formation of the desired cis D/Ering junction in a diastereomeric ratio of 10:1, the major diastereomer displaying the required C-3/C-14 to C-20 anti-diastereoselectivity. Subsequent global reduction and oxidation/E-ring formation processes afforded the target in 8 steps over 10 operations in 25% overall yield and in 96% enantiomeric excess. X-Ray crystallographic structure determination provided conclusive evidence for the formation of the target.

Abstract:
Drug discovery is reliant on new developments in natural product chemistry as well as advances in chemical synthesis. The interconnectivity and interdependence of natural and synthetic investigation in drug discovery is evident. The chemical exploration reported herein elaborates the relationship between natural product chemistry and chemical synthesis. Of particular interest are chemicals from organisms residing in less accessible environments, particularly Antarctica and endophytic microbial communities. Degradation via reductive ozonolysis of palmerolide A, a macrocyclic polyketide isolated from the Antarctic tunicate Synoicum adareanum, and subsequent synthetic preparation of the resulting polyols (1,2,6-hexanetriol and 1,2,3,6-hexanetetraol) led to a revision in the absolute configuration of the bioactive natural product (7R, 10R, 11R to 7S, 10S, 11S). A partial synthesis of palmerolide A (C3-14) was completed using Grubb’s 2nd generation catalyst to couple fragments formed using the previously developed methodology from the degradation study. Isolation of indole-pyrimidine containing alkaloids meridianins A, B, C, and E from the Antarctic tunicate Synoicum sp. prompted a synthetic investigation of psammopemmin A, a related alkaloid from the Antarctic sponge Psammopemma sp. resulting in reassignment of the structure of psammopemmin A to that of meridianin A. Both meridianin A and psammopemmin A were synthesized through a Suzuki coupling of the same 4-indolol nucleophile to the apposite pyrimidine electrophile. Several synthetic 3-pyrimidylindole analogs were also prepared and investigated for central nervous system, antimalarial, and cytotoxic activity. Chemical investigation of extracts from mangrove fungal endophytes that displayed antimalarial properties in vitro resulted in the isolation of several potent but cytotoxic and cytostatic compounds: cytochalasin D, roridin E, and 12,13-deoxyroridin E.

Full text
Abstract:
Includes bibliographical references.
he radical cyclisation of chiral 4,5-substituted N-acyl-2-aza-6-heptenyl radicals, derived from D-ribose, has been undertaken as a model stuay towards Tacaman indole alkaloid synthesis. The radical cyclisations were conducted using tributyltin hydride/AIBN in refluxing benzene. The α-acylamino radicals added to double bonds which were activated by an ethoxycarbonyl substituent. No reduction of the radicals by the tributyltin hydride was observed. Those radicals incorporating an isopropylidene ketal at the 4 and 5 positions as chiral auxiliary showed excellent regio- and stereoselectivity. Out of a possible 4 diastereomers, only two were obtained in a 2:8 ratio. It was established that the isopropylidene ketal directed the cyclisation stereoselectively and that no stereoselectivity was observed in the absence of the chiral auxiliary.
