| titleOfInvention | Preparation of alpha-substituted-alpha,beta-unsaturated carbonyl compound |
| abstract | PURPOSE: To prepare the titled compound in high yield and efficiency, by converting an α,β-unsaturated carbonyl compound to an enol silyl ether, reacting the ether with acetal, and oxidizing the resulting carbonyl compound having a phenyl-selenyl group at the β-position. n CONSTITUTION: An α,β-unsaturated carbonyl compound of formula I (R 1 WR 4 are H or 1W20C organic group; two of the R 1 WR 4 may form together a ring) is made to react with an acetal of formula II (R 5 is methyl, ethyl or benzyl; R 6 is H or 1W 20C univalent organic group; A is univalent organic group which may be same to or different from R 6 , or OR 5 ) in the presence of trialkyl- or triaryl-silyl trifluoromethanesulfonate, and the reaction product is made to react with a trialkyl- or triaryl-silylphenyl selenide in an inert organic medium to obtain a carbonyl compound of formula III, which is then oxidized to afford the objective compound of formula IV. n USE: Intermediate or prostaglandin compound, pharmaceuticals, pesticides, perfumery, etc. n COPYRIGHT: (C)1981,JPO&Japio |
