4-(Alkoxycarbonyl)-pent-4-enimidates were regioselectively synthesized via a copper-catalyzed four-component reaction of Baylis–Hillman adducts with terminal alkynes, sulfonyl azides and alcohols. The procedure is concise, general and efficient. The resulting pentenimidates could be further transformed to 3-methylene-2,3-dihydroindene-1-imidates.
4-(烷氧羰基)-戊-4-亚氨基酸酯是通过铜催化的Baylis-Hillman加合物与末端炔烃,磺酰基叠氮化物和醇的四组分反应区域选择性合成的。程序简明,通用,高效。可以将所得戊烯酰胺进一步转化为3-亚甲基-2,3-二氢茚-1-亚氨酸酯。
