Abstract A simple route is described for the synthesis of E and Z 3‐chloro‐2‐propenamides (4a‐e), esters (3a) and acids (2a‐c) by the reaction of 2,3‐acetylenic acids with oxalyl chloride in DMF followed by treatment of the corresponding 3‐chloro‐2‐propenoyl chloride derivative with amines, alcohol and water.
摘要描述了通过 2,3-炔酸与草酰氯反应合成 E 和 Z 3-氯-2-丙烯酰胺 (4a-e)、酯 (3a) 和酸 (2a-c) 的简单路线。在 DMF 中,然后用胺、醇和水处理相应的 3-氯-2-丙烯酰氯衍生物。
