Single diastereomers of β-keto phosphine oxides have been generated from intermolecular acylation of phosphine oxides using either chiral esters or chiral phoshine oxides. In most cases, reduction of the ketone products was not affected by the presence of extra chiral centres. Some mechanistic points of interest in the acylation reactions are discussed.
β-酮膦氧化物的单一非对映异构体是通过使用手性酯或手性膦氧化物通过膦氧化物的分子间酰化而产生的。在大多数情况下,多余的手性中心不会影响酮产品的还原。讨论了酰化反应中的一些机制。
