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.

Abstract: Preparation of optically active alpha-hydroxyketone derivatives of formula R-CHOH-CO-R (I) are prepared catalytically by benzoin condensation of aldehydes of formula RCHO (II) in the presence of a chiral triazolium carbene of formula (III). R = 1-30C aliphatic, cycloaliphatic, arylaliphatic, or aromatic; R1 = 1-30C alkyl or aryl (both optionally bonded by O, S or N), H, halo, CN, NO2 or 1-20C perhaloalkyl; R2, R3 = 1-30C alkyl or aryl; or R1+R3 complete a ring. R2 and/or R3 are chiral. (III) is preferably formed in situ, from a salt of formula (IV) or by elimination of HY from the triazoline of formula (V). X = anion;Y = group that can be lost as HY. (III), (IV) and (V) are new.

Abstract: A process is proposed for producing acyloines of general formula (I) in which R and R are identical or different and represent hydrogen or a C1-C20 alkyl, a C6-C10 aryl, a C7-C12 aralkyl, a heteroaryl, or a heterocycloalkyl group, these groups being substituted if appropriate, with the exception of formaldehyde autocondensation products. In the proposed process, an aldehyde of formula (II) R CHO is allowed to react with an aldehyde of formula (III) R CHO, in which R and R have the meanings indicated above and at least one of the groups R and R represents a group other than hydrogen, in the presence of catalysts produced using an auxiliary base from triazolium salts of formula (IV) in which R and R are identical or different and represent aliphatic groups with 1-30 carbon atoms, or, if appropriate, aryl groups, aralkyl groups and/or heteroaryl groups, these groups being substituted if appropriate; R represents hydrogen or the group R CH(OH); and A is the equivalent of a singly or multiply negatively charged anion for the electrical neutralisation of the triazolium cation charge.
