An efficient and versatile iron phthalocyanine catalyzed method has been developed for N-alkylation of various amines with alcohols. Readily available alcohols were used as alkylating agents for direct N-alkylation of aminobenzothiazoles, aminopyridines and aminopyrimidines. N-Alkylation of ortho-substituted anilines (–NH2, –SH and –OH) led to the synthesis of 2-substituted benzimidazoles, benzothiazoles
已经开发出一种有效且通用的铁酞菁铁催化方法,用于各种胺与醇的N-烷基化。现成的醇用作烷基化剂,用于氨基苯并噻唑,氨基吡啶和氨基嘧啶的直接N-烷基化。邻位取代苯胺(-NH 2,-SH和-OH)的N-烷基化反应可在一锅中合成2-取代的苯并咪唑,苯并噻唑和苯并恶唑。
