Abstract
Catalytic enantioselective tandem carbonyl ylide formation-cycloadditi on of alpha-diazo-beta-ketoesters 1 (R = alkyl, n = 1,2) using 1 mol% [Rh-2(S-DOSP)(4)] 2 in hexane at room temperature to give the cycloadd ucts 3 in good yields and up to 53% ee are described. (C) 1997 Elsevie r Science Ltd.
