Enantioselective approach to 13a-methylphenanthroindolizidine alkaloids.

Bo Su1, Chunlong Cai, Qingmin Wang.   

Abstract

The first enantioselective approach to 13a-methylphenanthroindolizidine alkaloids is reported, featuring an efficient stereoselective Seebach's alkylation and Pictet-Spengler cyclization. The proposed and other three most probable structures were ruled out, indicating hypoestestatin 1 needs further assignment.
