A highly efficient carboxylate-phosphate anhydride pathway is described for the direct, economical synthesis of esters and amides from carboxylic acids and alcohols or amines. The reaction proceeds with retention of configuration with both chiral secondary alcohols and α-amino acid derivatives allowing access to useful chiral auxiliaries, ligands, and organocatalysts. Ester and amide products can be isolated directly in high yield due to the water soluble nature of the side products.

Benzylation of chiral esters of N-acyglycines using various bases and additives was examined.No C-alkylation was observed with one equivalent of base.Diastereoselectivities were dependent on the amount of additive, the nature of the N-acyl group, and the chiral ester.A model to account for the degree and sense of the stereoselectivity is proposed.
