Abstract

The dimeric cinchona alkaloid (DHQD)2 PHAL is used to catalyze an effective asymmetric bromohydroxylation of unfunctionalized olefins with H2 O as nucleophile an N-bromobenzamide as a bromine source. A variety of optically active bromohydrins are formed with up to 88 % ee.

Keywords: bromination; cinchona alkaloids; enantioselectivity; olefins; water.
