Catalytic enantioselective synthesis of glutamic acid derivatives via tandem conjugate addition - Elimination of activated allylic acetates under chiral PTC conditions

A new, general, and practical procedure for the asymmetric synthesis of 4-alkylidenyl glutamic acid derivatives via a catalytic enantioselective tandem conjugate addition-elimination on allylic acetates under chiral phase-transfer conditions is reported.
