1 mol% of catalyst is sufficient: The hetero Diels-Alder reaction of α-imino esters 1 with activated conjugated dienes 2 (R=H, Me) needs only 1 mol% of a 2,2'-bis(diarylphosphanyl)-1,1'-binaphthyl (BINAP) copper(I) complex as the catalyst to generate the adducts 3 in good yields and with enantiosele
