Abstract: Preparation of hydantoins or aminoacid cyclic anhydrides (I) involves reacting an aldehyde (II) with carbon monoxide and a u or carbamate compound (III) in presence of a transition metal catalyst. Preparation of hydantoins or aminoacid cyclic anhydrides of formula (I) involves reacting an aldehyde RCHO (II) with carbon monoxide and a urea or carbamate compound of formula R3-NH-C(O)-R2 (III) in presence of a transition metal catalyst. X = O or NH; R = alkyl or aryl (both optionally substituted); R3 = H or as defined for R; R2 = group which reacts with the COOH group formed in the reaction under ring-closure to form (I).
