The efficient Dynamic Kinetic Resolution (DKR) of disubstituted anhydrides has been shown to be possible for the first time. Using an ad hoc designed organocatalyst and an enantio- and diastereoselective cycloaddition process with aldehydes, stereochemically complex γ-butyrolactone derivatives can be obtained – with control over three contiguous stereocentres, one of which is all carbon quaternary
二取代酸酐的有效动态动力学拆分(DKR)首次被证明是可行的。通过使用特设的有机催化剂以及对映体和非对映体与醛的选择性加成环合方法,可以获得立体
