Abstract A facile, rapid, efficient, and column chromatography-free protocol for the synthesis of tetrahydrobenzo[b]pyranderivatives via a one-pot three-component reaction using MgSO4 in dimethyl sulfoxide (DMSO) has been achieved. This protocol has a simple experimental procedure, good functional group tolerance, broad substrate scope, and high yields in a short reaction time.
摘要 已经实现了使用 MgSO 4在二甲基亚砜 (DMSO) 中的一锅三组分反应合成四氢苯并[ b ] 吡喃衍生物的简便、快速、高效且无柱层析的方案。该方案实验程序简单,官能团耐受性好,底物范围广,反应时间短,收率高。
