SYNTHESIS OF TYLOPHORINE

A biogenetic type of synthesis of tylophorine 12 (3.8percent yield, established by a radio-dilution method) was achieved by ferricyanide oxidation of 6,7-di(3-hydroxy-4-methoxyphenyl)-6,7-dehydroindolizidine 10.

Synthesis of Substituted 6,7-Diphenyl-1,2,3,5,8,8a-hexahydroindolizines

Substituted 6,7-diphenyl-1,2,3,5,8,8a-hexahydroindolizines (28a to 28e) have been synthesized by two methods.In first method, condensation of substituted 2-phenacylpyrrolidines (24b to 24d) with substituted phenylacetylchlorides (2) affords substituted 2-
