A general and highly chemo‐, regio‐, and stereoselective synthesis of α,β‐unsaturated aldehydes by a domino hydroformylation/aldol condensation reaction has been developed. A variety of olefins and aromatic aldehydes were efficiently converted into various substituted α,β‐unsaturated aldehydes in good to excellent yields in the presence of a rhodium phosphine/acid–base catalyst system. In view of the
已经开发了通过多米诺加氢甲酰化/羟醛缩合反应进行的一般的,高度化学,区域和立体选择性的α,β-不饱和醛合成反应。在铑膦/酸碱催化剂体系的存在下,各种烯烃和芳族醛均以良好或优异的收率有效地转化为各种取代的α,β-不饱和醛。考虑到底物的易获得性,高原子效率,出色的选择性和温和的条件,该方法有望补充目前制备α,β-不饱和醛的方法。
