摘要

Abstract A one-pot reaction of Boc-protected amino alcohols and 2-sulfobenzoic anhydride followed by the addition of a wide variety of primary amines has allowed rapid access to diverse libraries of amidosulfonates 1, 2-C 6 H 4 (SO 3–)(COCHR 1 CH 2 NH 2+ R 2)(R 1= Bn, iPr, Ph; R 2= aryl, CHMePh, 1-adamantyl), of which two examples have been characterised by X-ray crystallography. These reactions proceed by SN 2 opening of ...
