Efficient tandem synthesis of 3-alkylaminoprop-2-enamides from 3-trimethylsilylprop-2-ynamides
摘要:
A tandem synthetic approach to previously unknown 3-aminoprop-2-enamides has been developed. It is based on Si-C (sp) desilylation of 3-trimethylsilylprop-2-ynamides and subsequent addition of an amine to the triple bond of intermediate terminal propynamides. The effects of the reaction conditions and amine nature on the efficiency of the process have been studied.
