H. Kotsuki et al., SYNTHESIS OF NOVEL CHIRAL DIAZOLE LIGANDS FOR ENANTIOSELECTIVE ADDITION OF DIETHYLZINC TO BENZALDEHYDE, Tetrahedron : asymmetry, 6(11), 1995, pp. 2665-2668
A variety of chiral pyrazole and imidazole derivatived ligands have be
en prepared under high pressure conditions and their catalytic efficie
ncy in the enantioselective addition of diethylzinc to benzaldehyde ha
s been examined.
