摘要

Summary: Readily prepared P-tosylethylamine (3) can be used to synthesize N-tosylethyl (TSE)-protected amido compounds and P-lactams, which can be deprotected under mild conditions with potassium tert-butoxide. ... Relatively few generally useful nitrogen protecting groups are currently available for amides, carbamates, and related functiona1ity.l In this paper we demonstrate the utility of P-tosylethylamine (3) in the synthesis of various N-protected P-tosylethyl ...
