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).

Abstract: Novel esters of specific formulas are new. Novel esters of formulae (Ia) and (Ib) , their esters, optically active forms, tautomers, racemates, distereomer mixtures or salts are claimed: R = phenyl or 1-6C alkyl or alkoxyalkyl, where the alkoxy is a combination of an alkoxy group with an oxygen atom, e.g. (m)ethoxy, propoxy, butoxy or pentoxy. Independent claims are included for: (1) preparation of these esters and their mixtures by radically reacting an acetate of formula (II) with 1,9-decandiene; (2) preparation of 1,15-hexadecadiones by reacting the ester of (II) with 1,9-decandiene and decarboxylating; (3) preparation of muscones of formula (III) by further reacting this product in the gaseous phase to give muscones, cyclizing in a mixture with unsaturated muscone derivatives and hydrogenating to muscone.
