Chiral N-acyloxazolidinones derived from conjugated dienoic acids undergo boron-mediated aldol condensation in good yield and with high regio- and diastereoselectivity to provide a convenient method for introducing a 1,3-diene subunit. The condensation of a homologous triene derivative is also described.
衍生自共轭二烯酸的手性N-酰基恶唑烷酮以高收率,高区域选择性和非对映选择性地进行硼介导的羟醛缩合,从而为引入1,3-二烯亚基提供了便利的方法。还描述了同源三烯衍生物的缩合。
