Abstract

In the first part of this minireview a variety of efficient asymmetric catalyses using heterobimetallic complexes are discussed. Since these complexes function at the same time as both a Lewis acid and a Bronsted base, similar to enzymes, they make possible many catalytic asymmetric reactions such as nitroaldol, aldol, Michael, Michael-aldol, hydrophosphonylation, hydrophosphination, protonation, epoxide opening, Diels-Alder and epoxidation reactions of alpha,beta-unsaturated ketones. in the second part a catalytic asymmetric cyanosilylation of aldehydes promoted by complexes displaying a Lewis acidity and a Lewis basicity is described.
