One-Pot Synthesis of 3-(Trimethylsilyl)propynamides
摘要:
A highly efficient one-pot procedure was developed for the synthesis of 3-trimethylsilylpropynamides by acylation of amines with trimethylsilylpropynoyl chloride generated in situ. Selective N-acylation and N,O-bis-acylation of -amino alcohols with formation of, respectively, N-(hydroxyalkyl)propynamides and 2-methyl-2-[3-(trimethylsilyl)propynoylamino]propyl 3-(trimethylsilyl)propynoate were accomplished with high yields.
