A simple and versatile method for the synthesis of 1,5-benzodiazepines is via condensation of o-phenylenediamines (OPDA) and ketones in the presence of catalytic amount of H-MCM-22 using acetonitrile as solvent at room temperature. In all the cases, the reactions are highly selective and are completed within 1-3 h. The method is applicable to both cyclic and acyclic ketones without significant differences. The reaction proceeds efficiently under ambient conditions with good-to-excellent yields.
一种简单且通用的合成1,5-苯二氮䓬的方法是,在室温下以乙腈为溶剂,在催化量的H-MCM-22存在下,使邻苯二胺(OPDA)与酮进行缩合反应。在所有情况下,反应具有高度选择性,且在1-3小时内完成。该方法适用于环状和非环状酮,且无显著差异。该反应在环境条件下高效进行,产率良好至优异。
