An unprecedented protocol for the synthesis of formate esters has been developed by employing N,N-dimethylformamide (DMF) as both the source of CHO and solvent. This reaction undergoes ring opening of the cyclopropyl carbinols and in situ formation of homoallylic alcohols, which reacts with DMF to give the desired products. The substrate cyclopropyl carbinols with different groups participate smoothly in this process and the desired products are obtained in moderate to good yields.

CuBr ₂催化环丙基甲醇与DMF的开环/甲酰化反应合成甲酸酯

通过使用N，N-二甲基甲酰胺（DMF）作为CHO和溶剂的来源，已经开发出前所未有的合成甲酸酯的方法。该反应经历环丙基甲醇的开环反应并原位形成均烯丙基醇，后者与DMF反应生成所需的产物。具有不同基团的底物环丙基甲醇顺利参与该过程，并以中等至良好的收率获得了所需的产物。
