摘要

An efficient synthesis of secondary carboxamides carrying ω-substituted ethyl and propyl groups on nitrogen atom has been developed which highlights nucleophilic ring opening of 2-methyl-2-oxazoline, 2-methyl-2-oxazine, and their derivatives with (CH 3) 3 SiX and HX (X= Cl, N 3, SeC 6 H 5, SC 6 H 5) type reagents.
