Abstract:

Synthesis of 4-Benzo[1,3]Dioxol-5-Ylthieno-[2,3-b]Pyridines 4,7-Dihydrothieno[2,3-b]pyridine 4 and thieno[2,3-b]pyridine 6 were obtained by Thorpe-Ziegler cyclization. Mn(OAc)3/acetic acid system had been used for oxidation of 1,4-dihydropyridine 3 to pyridine derivative 5. 6-Carbamoylmethylsulfanyl-1,4-dihydropyridine 3 was prepared by al-kylation of piperidinium 1,4-dihydropyridine-2-thiolate 1 with iodoacet-amide.

Abstract:

Make 5-methoxy-2-mercapto-imidazo[4,5-b]pyridine and 2-chloro-3,5-dimethyl-4-methoxy-pyridine hydrochloride as the starting materials, in alkaline conditions, use nucleophilic substitution to generate the prochiral sulfide: 2-[2-(4-methoxy-3 ,5-dimethyl-pyridine) methylmercapto]-5-methoxy-imidazo [4,5-b] pyridine. After recrystallization twice, gain the product with the yield of 80%, and the purity of 99.6% and above. Then make D-(-)-diethyl tartrate and tetraisopropyl titanate as the chiral reagents, in alkaline conditions, use cumene hydroperoxide oxide to oxidize prochiral sulfide, for synt

Abstract:

Pyrazolo[3,4-b]pyridine derivatives 7 and 9 were synthesized via the reaction of 3-amino-1H-pyrazolo-[3,4-b]pyridine derivative 2 with ω-bromoacetophenones. Reaction of 7 and 9 with Ac2O afforded the imidazo[1',2':1,5]py razolo[3,4-b]pyridine derivative 8 and pyrazolo[3,4-b]pyridine derivative 10, respectively. Reaction of 2 with chloroacetonitrile followed by DMF-DMA gave imidazo[1',2':1,5]pyrazolo[3,4-b]pyridines 4 and 5, respectively. Acetyl acetone and 1,1-dicyano-2,2-dimethylthioethene were reacted with 2 to afford the pyrido[2',3':3,4]pyrazolo-[1,5-a]-pyrimidines 11 and 14, respectively.
