THE ASYMMETRIC MICHAEL ADDITION PROCESS INVOLVING CHIRAL IMINES : STEREOCHEMICAL DATA IN SUPPORT OF A CYCLIC-LIKE TRANSITION STATE

Article abstract of DOI:10.1016/0040-4039(88)85255-9

Addition of imine 4 to Michael acceptors 5 and 8 are both highly selective processes.The observed stereocontrol of the newly created asymmetric centers in the resulting adducts strongly supports cyclic-like transition states.
