We have developed two new procedmea for the dtrect converston of e&are to secondary am&b. In our first procedure, secondary amides can be prepared in 8348% yield starting from glycol esters. Addition of Sn[NU'MS)~2 and a primary amine to the glycol ester generates an intermediate tin(III alkoxy amid
