Outline of Final Research Achievements |
A synthetic method of alpha-alkylidene-beta-oxo imides and their catalytic asymmetric reactions ([4+2] and [2+2]cycloadditions, Mukaiyama-Michael reaction, Hosomi-Sakurai-Michael reaction, and Friedel-Crafts reaction) have been successfully developed. alpha-alkylidene-beta-oxo phosphonates were found to show the similar property as those of alpha-alkylidene-beta-oxo imides in Mukaiyama-Michael reaction. Using alkenes doubly activated by ketone and ester, an enantioselective total synthesis of (R)-homosarcomnycin, and a first enantioselective total synthesis and structural elucidation of (-)-bucidarasin A and C have been successfully achieved.
