efficient protocol for the synthesis of thioesters-functionalized 2-benzopyrans has been developed through a palladium-catalyzed one-pot cyclization/thiocarbonylation reaction of propargyl ethers with sulfonyl chlorides as promising and easily accessible sulfur sources. The reaction showed good compatibility towards versatile functional groups, both aryl and alkylsulfonyl chlorides were well tolerated. Without
通过钯催化的炔丙基醚与磺酰氯的一锅环化/硫代羰基化反应,开发了一种通用且有效的合成硫酯官能化 2-苯并吡喃的方案,磺酰氯是有前途且易于获得的硫源。该反应对多种官能团表现出良好的相容性,芳基和烷基磺酰氯均具有良好的耐受性。在没有任何外部还原剂的情况下,使用Mo(CO)作为方便的CO源,以中等至良好的收率获得了各种带有硫酯作为有吸引力的官能团的2-苯并吡喃。
