Condensation of Chiral lmines and Chiral ]]-Enaminoesters with Maleic and Citraconic Anhydrides

Abstract

Condenmlions of chiral imines I and 4, and chiral ennminoesters 10 and 13. ~ ma/e~ and citracoaic anhydrides were reported. These experimen:al om~com~ can be ratio _l~__~ed by invaking the compact, eado-aplaroaches of the two reactants 18.
