Abstract
A very fast, microwave-assisted formation of carboxylic esters via reaction of carboxylic acids with O-alkylisoureas derived from primary and secondary alcohols proceeds in good yields with clean inversion of configuration where appropriate. The reaction works well with very hindered carboxylic acids.
