标 题 :Process for the preparation of esters of leukotriene A
发明人：GLEASON JOHN G; KINZIG CHARLES M; BRYAN DEBORAH L
权利人:SMITHKLINE BECKMAN CORP
摘要:Esters of leukotriene A are conveniently prepared by reacting 9-oxo-5,6-trans-epoxynon-7(E)-enoates with 11-triphenylphosphoranylidene undec-6(Z),9(Z)-diene. Esters of leukotriene-A are useful intermediates in the synthesis of naturally occurring leukotrienes, which have been shown to be potent broncho-constricting substances. Novel intermediates to the esters of leukotriene A. 9-oxo-5,6-trans-epoxynon-7(E)-enoates and 7-oxo-5,6-trans-epoxyheptanoates, are disclosed.

权利人:NISSAN CHEMICAL IND LTD; SATO FUMIE
摘要:A cis-olefin of the formula: R 1 —CHâ•?CH—R 2 is prepared by reducing an alkyne of the formula: R 1 —C≡C—R 2 with formic acid in the presence of a palladium catalyst. R 1 and R 2 are independently selected from the group consisting of a hydrogen atom, ester group, substituted silyl group, carboxyl group, cyano group, aliphatic C1-C20 hydrocarbon group, and phenyl group. The cis-olefin which is a useful intermediate for the synthesis of fine chemicals is selectively produced in high yields.

摘要:Allenic esters of the formula: ##EQU1## (specific examples of R, R 1 , R 2 , R 3 and R 4 are given) and a process for the preparation thereof which comprises reacting propargyl alcohol derivatives with 2-substituted ortho-acetic acid esters in the presence of an acidic catalyst. These allenic esters are rearranged in the presence of an alkali catalyst to form α, β, γ, δ-unsaturated carboxylic acid esters and are useful as intermediates in the synthesis of various perfumes, medicines, agricultural chemicals and the like.
