An Asymmetric Synthesis of the Ant Venom Alkaloid(3S,5S,8aR)-3-Butyl-5-(4-pentenyl)indolizidine via the Sharpless Asymmetric Dihydroxylation
摘要:
The first asymmetric synthesis of the ant venom alkaloid (3S,5S,8aR)-3-butyl-5-(4-pentenyl)indolizidine (1) has been performed by starting with the Sharpless asymmetric dihydroxylation of N-alkenylcarbamate (3) followed by reductive annulation (5-exo-tetrahedral).
