Asao-Yamamoto苯环化

概要

Asao-Yamamoto苯环化 (Asao-Yamamoto benzannulation)是在三卤化金[1]-[3]、AuNPore (nanoporous gold)[4]、三氟甲磺酸铜[2]-[3], [5]、卤化铜[5]或氯化锌[6]催化条件下,通过邻炔基苯甲醛或烯基炔醛 (enynal)与各类炔基化合物之间的分子间[1]-[2], [4]-[11]或分子内[3]的形式[4 + 2]苯环化过程 (formal [4 + 2] benzannulation),获得一系列萘环或苯环化合物的反应。该反应由日本Tohoku大学理学院化学系 (東北大学理学部化学教室, Department of Chemistry, Graduate School of Science, Tohoku University)的Asao (浅尾 直樹,Asao Naoki)与Yamamoto (山本 嘉則,Yamamoto Yoshinori)在2002年首次报道[1]

Asao-Yamamoto苯环化反应具有优良的产率、温和的反应条件与优良的区域选择性。在各类萘环或苯环化合物[1]-[4], [7]-[11]、卤代与多卤代芳烃[5]-[6]、聚苯类共轭聚合物[12]的构建以及生理活性天然产物的全合成[13]中具有广阔的应用前景。
