  作者：Wei Zhao、Patrick K. Yan、Alexander T. Radosevich

  DOI：10.1021/ja511889y

  日期：2015.1.21

  A small-ring phosphacycle is found to catalyze the deoxygenative condensation of α-keto esters and carboxylic acids. The reaction provides a chemoselective catalytic synthesis of α-acyloxy ester products with good functional group compatibility. Based on both stoichiometric and catalytic mechanistic experiments, the reaction is proposed to proceed via catalytic P(III)/P(V)═O cycling. The importance
