A Diastereoselective Cyclic Imine Cycloaddition Strategy To Access Polyhydroxylated Indolizidine Skeleton: Concise Syntheses of (+)-/(−)-Lentiginosines and (−)-2-epi-Steviamine
摘要:
We describe in this paper the development of a novel diastereoselective cyclic imine cycloaddition strategy to access the polyhydroxylated indolizidine skeleton and its application in the concise syntheses of (+)-/(-)-lentiginosines and (-)-2-epi-steviamine.
