(catalytic) asymmetric synthetic methodologies occupy an important position in modern organic synthesis, the catalytic cleavage of a chiral auxiliary remains underdeveloped. We report the Ni(cod)2/bipyr.-catalyzed alcoholysis of N-acyloxazolidinones to deliver esters. The reaction is broad in scope for both N-acyloxazolidinone substrates and alcohol nucleophiles, and displays good functional group tolerance
尽管基于N-酰基氧杂唑烷酮的(催化)不对称合成方法在现代有机合成中占有重要地位,但手性助剂的催化裂解仍未开发。我们报告了N(酰基)xx恶唑烷酮的Ni(cod)2 /联吡啶催化的醇解反应以递送酯。该反应对于N-酰基氧杂唑烷酮底物和醇亲核试剂都具有广泛的范围,并且显示出良好的官能团耐受性和优异的化学选择性。克级的甲醇分解作用可以使强效免疫抑制剂FK506的紧密类似物的C22–C26片段进行对映选择性合成。
