A very mild, one-step esterification using nearly equimolar amounts of N-protected amino acids and alcohols, in conjunction with 1-tert-butoxy-2-tert- butoxycarbonyl-1,2-dihydroisoquinoline (BBDI) as a novel condensing reagent is described.

It has been shown that di-tert-butyl pyrocarbonate can be used as a condensing reagent in the production of anhydrides and some aryl esters of carboxylic acids.The synthesis of anhydrides and of phenyl, p-nitrophenyl, β-naphtyl, and quinolin-8-yl esters of N-protected amino acids is described.
