Reactions of α-ethoxycarbamates (α-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 des

Trimethylsilyl trifluoromethanesulfonate (TMSOTf) catalyzed addition of 1-trimethylsilyloxy-1-phenylethene to N-ethoxycarbonyl- and N-tert-butoxycarbonyl-2-ethoxypiperidines (3a and 3b, respectively) afforded the corresponding ketocarbamates 4a and 4b, in excellent yields. Stereoselective conversion to (±)-norsedamine (7) and (±)-sedamine (8) is described.
