Abstract

A design of a chiral organocatalyst is very important for obtaining of a chiral product with a high optical purity in a catalytic asymmetric reaction. Recently, we developed a series of chiral β-amino alcohol organocatalysts A that showed high level of catalytic activity in some asymmetric reactions. These β-amino alcohols are stable in air, and have two advantageous features, easy preparation and exhibiting high stereoselectivity in an enantioselective reaction. This review summarizes our recent works involving the Diels-Alder (DA) reactions of 1,2-dihydropyridines, anthrones or 3-hydroxy-2-pyridones as dienes with dienophiles, the asymmetric 1,3-dipolar cycloaddition of nitrones with α,β-unsaturated aldehydes and the crossed aldol reaction of isatins with acetaldehyde, by the use of the simple primary β-amino alcohols as efficient chiral organocatalysts for the asymmetric reactions.
