SYNTHESIS OF SOME ANALOGS OF ABSCISIC ACID FROM 3-CYCLOHEXENE-1-CARBALDEHYDE AND ITS METHYL HOMOLOGS

The E,E and Z,E isomers of 5-substituted 3-methyl-2,4-pentanedioic acids were synthesized from 3-cyclohexene-1-carbaldehyde and its methyl homologs.The possibilities of their production by the Reformatsky and Wittig reactions or by condensation of substituted 3-cyclohexene-1-carbaldehydes with diethyl β-methylglutaconate were investigated.It was shown that the last path makes it possible to obtain the Z,E isomers preferentially.

Process for preparing ketones using zinc acetate condensation catalysts, products produced thereby and organoleptic uses of same

Described is a process for the production of alpha, beta unsaturated ketones by reaction of an aldehyde with a ketone in the presence of a catalyst consisting essentially of either zinc acetate or zinc acetate dihydrate. The ketones obtained are suitable and some cases as solvents and in some cases as intermediates for the production of valuable odorants, dyes, plastics and especially nature-identical substances and are also useful as odorants per se.
