mercaptoacetate triggered benzannulation reaction is described. The precursors are heterocyclic, aromatic or acyclic compounds bearing a carbonyl group at ortho position to an internal alkyne. The methodology does not require transition-metal catalysts and moreover it is general for the preparation of wide range of benzo-annelated heterocycles, naphthalenes and benzenes.
描述了新颖,高效,强大的巯基乙酸甲酯触发苯环化反应。前体是在内部炔烃的邻位带有羰基的杂环,芳族或无环化合物。该方法不需要过渡金属催化剂,而且通常用于制备各种苯并-退火的杂环,萘和苯。
