Abstract

A simple, efficient, stereoselective, and in some cases usefully nonregioselective method for the synthesis of β-azido alcs. by the direct opening of 1,2-epoxides with 1,1,3,3-tetramethylguanidinium azide (TMGA) in CH3CN, catalyzed by simple transition metal-based salts [Hf(OTf)4, Zr(OTf)4, Yb(OTf)3], is described.  Also, TMSN3 may be used in some reactions as a source of N3-.  This new method appears to be competitive with other methods previously reported.
