Paragraph 0135-0136; 0143, (2017/05/03)
The present invention relates to a compound for inhibiting lipid oxidation, and a producing method thereof. The compound for inhibiting lipid oxidation is synthesized by a transesterification reaction though a vinyl reaction and a lipase-catalyzed reaction. The produced compound for inhibiting lipid oxidation has an excellent effect of inhibiting oxidation according to a total oxidation value (TOTOX) which is a combination of a P-anisidine value (P-AnV) and a peroxide value (PV) and an analysis of a thiobarbituric acid reaction substance (TBARS).COPYRIGHT KIPO 2016

Methyl α-d-glucopyranoside as a model acceptor was acylated by several phenolic and non-phenolic vinyl esters using immobilised Lipolase. Donor specificity and regioselectivity of reaction were investigated. Conversion and rate of acylation by structurally varied donors indicates that the synthetic reactivity of Lipolase corresponds to the hydrolytic activity of feruloyl esterase type A. Lipolase exhibited remarkable regioselectivity for primary position of methyl α-d-glucopyranoside. The acylation occurred exclusively at 6-O primary position when vinyl esters of phenolic acids (hydroxybenzoates, hydroxyphenylalkanoates and hydroxycinnamates) served as acyl donors (5-77%). In addition to the major 6-O-acyl products (52-79%), 2,6-di-O-acylated derivatives were isolated from reaction mixtures (2-13%) when non-phenolic donors were used (vinyl esters of fully methoxylated derivatives of phenolic acids, along with vinyl benzoates, cinnamates or some heterocyclic analogues).

In this paper, the copper(II)-catalyzed esterification reaction of arenecarboxylic acids with aryl- or vinyl-substituted trimethoxysilanes is described. A series of aryltrimethoxysilanes and arenecarboxylic acids worked well under this procedure, affording aryl benzoate derivatives in moderate to good yields. Notably, trimethoxy(vinyl)silanes also worked well under this procedure giving a facile and versatile method to access vinyl benzoate derivatives. Georg Thieme Verlag Stuttgart.
