Polymer-supported Oxone and tert-butyl hydroperoxide: new reagents for the epoxidation of α,β-unsaturated aldehydes and ketones
摘要:
Efficient, mild and selective epoxidation of alpha,beta-unsaturated aldehydes and ketones was performed using polyvinylpyrrolidone-supported Oxone (Oxone/PVP) and Bu(t)OOH/PVP.

A novel, versatile one-step synthesis of o-dichlorobenzaldehydes has been developed. Acyclic alpha,beta-epoxy ketones undergo the Vilsmeier reaction to afford o-dichlorobenzenemono- and dicarboxaldehydes whereas cyclic alpha,beta-epoxy ketones gave o-dichlorobenzenecarboxaldehydes and chlorobenzenedicarboxaldehydes.
