Addition reactions of organolithium and Organocopper reagents to δ-oxygenated α,β-unsaturated carbonyls, derived from glyceraldehyde acetonide, have been studied. In most cases there is a strong preference for conjugate addition of the organometallic reagent. Organocopper reagents react with anti stereoselectively, whereas most organolithium reagents react with syn stereoselectivity, except for phenyllithium
研究了有机锂和有机铜试剂与衍生自甘油醛丙酮化物的δ-氧化的α,β-不饱和羰基的加成反应。在大多数情况下,强烈优选共轭添加有机金属试剂。有机铜试剂与反立体选择性反应,而大多数有机锂试剂与顺立体选择性反应,除了苯基锂例外。
