Efficient synthesis of a range of benzosubstituted macrocyclic diamides
Abstract:
Some new macrocyclic dibenzotetraoxadiamides, tribenzotetraoxadiamides,tribenzopentaoxadiamide, tribenzohexaoxadiamide, and tetrabenzoheptaoxadiamide 15-22 have been prepared. These compounds were obtained in the macrocyclization step byreacting the diamines 6 and 7 with appropriate dicarboxylic acid dichlorides 8-14. Thecyclization does not require high dilution techniques or template effect and provides theexpected dilactams in high yields ranging from 63% to 81%.
