Tetrahedron Letters | 1997

A convenient synthesis of enaminones using tandem acetonitrile condensation, Grignard addition

Anthony R. Haight; Timothy L. Stuk; Jerome A. Menzia; Timothy A. Robbins

Abstract Condensations of N,N-dibenzyl α-amino esters with the anion of acetonitrile followed by the addition of a Grignard reagent proceed in excellent yields. This affords rapid access to the peptidomimetic precursor α-amino enaminones in one pot from the esters.
