报道了钯催化β-内酯与各种类型的胺(伯胺、仲胺和芳基胺)开环以提供对酰基C-O键断裂具有优异选择性的β-羟基酰胺。该方案的实用性在提供对映体富集的α-亚甲基-β-内酯的不对称动力学拆分中得到了证明
A Pd-catalyzed ring-opening of β-lactones with various types of amines (primary, secondary and aryl) to provide β-hydroxy amides with excellent selectivity towards acyl C–O bond cleavage is reported. The utility of this protocol is demonstrated in an asymmetric kinetic resolution providing enantioenriched α-Methylene-β-lactones
