New Asymmetric Synthesis of Enantiomeric Pairs of the 2-Substituted Pyrrolidines Bgugaine and Irniine
摘要:
A new asymmetric route to 2-substituted pyrrolidines starting with the Sharpless asymmetric dihydroxylation (AD) of 4-pentenylphthalimide (5) followed by aminocyclization of the resultant amino alcohol is presented. The application to the asymmetric synthesis has been examined for two 2-substituted pyrrolidine alkaloids, bgugaine (1) and irniine (2).
