Interaction of C-Alkylsubstituted-1,5,10,14-tetraazacyclooctadeca-4,13-diene with Carboxylic Acid Halides As a New Method for the Synthesis of C- and N-Acyl-2,3,6,7,8,9-hexahydro-1H-1,5-diazonines
摘要
Abstract
The reactions of 2,2,4,11,11,13-hexamethyl-1,5,10,14-tetraazacyclooctadeca-4,13-diene with carboxylic acid chlorohydrides produced C- and N-acyl substituted 2,3,6,7,8,9-hexahydro-1H-1,5-diazonines. The structure of the obtained C- and N-acyldiazonines was studied by 1H and 13C NMR spectroscopy using two-dimensional experiments 1H-13C HMQC, HMBC, 1H-1H COSY.
