compounds and related acceptor-substituted olefins derived from myrtenal as ex chiral pool source. Monophosphanes with astereogenic as well as stereogenic phosphorus are described. In addition diphosphanes were prepared by a highly diastereoselective double conjugate addition of a secondary diphosphane. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
通过将膦以高度非对映选择性加成到 α,β-不饱和羰基化合物和衍生自桃金娘烯醛的相关受体取代烯烃作为手性池源,制备了多种新型手性膦。描述了具有立体生成和立体生成磷的 Monophosphanes。此外,二膦是通过高度非对映选择性双共轭加成仲二膦制备的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
