摘要:α,β-Unsaturated aldehydes are useful products as such in agrochemistry, but also potential intermediates for the preparation of important insect pheromones and kairomones. Until now, primarily the thermodynamically more stable (E)-α,β-unsaturated aldehydes have been identified as useful intermediates in the production of conjugated diene pheromone compounds, however, their practical and cost-effective synthesis on an industrial scale remains challenging. The problem to be solved by the present invention is to provide a method for selective oxidation of alkenes to α,β-unsaturated carbonyls which can be further transformed into pheromones and kairomones preferably without isolation and significant loss of the existing stereochemical purity.

摘要:Methods are provided for preparing all four diastereomers of 2-alkyl-3-hydroxyalkanals, 2-alkyl-3-silyloxyalkanals, and the like, with high enantiocontrol, using non-aldol chemistry. The synthetic methods also provide novel, stereospecific routes to polypropinates and chiral 2-substituted-1,3 diols.

摘要:Hexadecyl cis-9-tetradecenoate commonly known as Cetyl myristoleate (CMO) is being used for the treatment of osteoarthritis and other joint inflammatory diseases, cis-9-Tetradecenoic acid (cis-9-myristoleic acid) is the main precursor for the preparation of CMO. As there are limited natural plant sources for cis-9-tetradecenoic acid, the present invention aimed at the synthesis of cis-9-tetradecenoic acid methyl ester from oleic acid methyl ester. As oleic acid is not available in pure form, this has to be isolated from oleic acid-rich oils like olive oil. cis-10-Tetradecenoic acid methyl ester, an isomer of cis-9-tetradecenoic acid was also prepared from undecenoic acid methyl ester, a derivative of castor oil. Undecenoic acid is easily available commercially in pure form. Hexadecyl cis-9-tetradecenoate and hexadecyl c/s-10-tetradecenoate were prepared by enzymatic transesterification of cis-9-tetradecenoic acid methyl ester and cis-10-tetradecenoic acid methyl ester with 1-hexadecanol (cetyl alcohol) respectively. Both the isomers of cetyl myristoleate were evaluated for anti arthritis, blocking inflammation and reduction of adjuvant-induced arthritis in rats.
