Conjugate addition diorganozinc reagents

Woodward et al. have used the binaphthol-derived ligand 40 in asymmetric conjugate addition reactions of dialkylzinc to enones [46]. Compound 40 has also been studied as a ligand in allylic substitutions with diorganozinc reagents [47]. To allow better control over selectivity in y substitution of the allylic electrophiles studied, Woodward et al. investigated the influence of an additional ester substituent in the jS-position (Scheme 8.25). [Pg.282]

Conjugate addition. The parent chiral BINAMINE is an excellent ligand for CUCI2 to promote the conjugate addition of diorganozinc reagents. When complexed to carbene 3 palladium dicarboxylates exhibit catal3dic activity in the aryl transfer from ArB(OH)2 to... [Pg.15]
