Effect of Tin(II) Triflate on Reactions of a-Ethoxycarbamates with Enolates
摘要:
Reactions of alpha-ethoxycarbamates (alpha-ethoxylated derivatives of N-ethoxycarbonylpyrrolidine, -piperidine, and -hexamethyleneimine) with various enolates (enol acetates, enol ethers, or tin(II) enolates of ketones) in the presence of tin(II) triflate are described.
