摘要

The novel ring-opening reaction of various 2-alkyl-and 2, 2-dimethyl-N-(diethoxyphosphoryl) aziridines (1) and (10) with copper-modified Grignard reagents proceeds regiospecifically at the less hindered carbon. The diethyl N-sec-alkylphosphoramidates (2) thus obtained may efficiently be converted to primary sec-alkylamine hydrochlorides (3) by refluxing with 20% hydrochloric acid. 2, 3-Disubstituted N-phosphorylated aziridines except N- ...
