N-acyl derivatives of formula R -C(O)N(H)C(R )X (I) are prepared by reacting, in the presence of a compound of formula R -COOH (II), a carbonic acid amide of formula R -CONH2 (III) and a glyoxalmonoacetal derivative of formula R C(O)C(OR )OR (IV). R , R = H or optionally substituted alkyl or aryl; R ,R = 1 - 12C alkyl; and X = CH(OR ) or COOR . An Independent claim is also included for a compound of formula R -C(O)N(H)C(R )C(OR )OR (V).
