Abstract

... [4] A catalytic asymmetric direct Michael reaction with atom economy would be more desirable in organic synthesis. ... higher chemoselectivities than those with electron-withdrawing groups, such as chloro or bromo (entries 5-7 and 13-16). ... 5-Oxo-5-phenyl-3- p -tolylpentanal (3c). ...
