A facile access to the synthesis of alkyl and aryl oxime esters of ketoximes and aldoximes in high yields (90-97%) is reported. The reactions were performed using N-[3-(methylamino)propyl]-N′-ethylcarbodiimide hydrochloride (EDCI) reagent in the presence of 4-(dimethylamino)pyridine (DMAP) as a catalyst at room temperature. The isolation and purification of products is very simple and in cases where product is solid, column chromatography is avoided. Georg Thieme Verlag Stuttgart New York.

A facile zinc-mediated Barbier-type allylation of aromatic aldoxime esters, producing the corresponding protected homoallylic hydroxylamines, which are readily converted into homoallylic hydroxamic acids, is described.

The present invention relates to novel O-acyloxime derivatives, a preparation method thereof and a pharmaceutical composition comprising the same for prevention and treatment of cardiovascular disease. The O-acyloxime derivatives according to the present invention may valuably be used for prevention and treatment of cardiovascular diseases such as hyperlipidemia, coronary arterial heart disease, atherosclerosis, and myocardial infarction caused by Lp-PLA2, because they have excellent inhibitory effect of Lp-PLA2.

A series of multi-substituted oximes were prepared and their potencies for inhibiting lipoprotein-associated phospholipase A2 (Lp-PLA2) activity were evaluated in vitro. Among them, compounds 3a, 3b, and 3m were identified to display a micromolar potency for inhibiting Lp-PLA2 in whole human plasma and isolated human LDL. Based on these results, structure-activity relationship was studied on modification of three parts of R1, R2, and R3 to identify a potent pharmacophore for Lp-PLA2. In an attempt to introduce various functional groups at R2 and R3, we discovered that replacement of less lipophilic groups led to an increase of inhibitory activity. Among the tested oxime derivatives, cyano- and morpholino-substituted analogue 4f at R2 and R3 had the highest potency with an IC50 value of 0.05 μM in whole human plasma.
(E)-Phenyl- and -heteroaryl-substituted O-benzoyl-(or acyl)oximes as lipoprotein-associated phospholipase A2 inhibitors

A series of (E)-phenyl- and -heteroaryl-substituted O-benzoyl- (or acyl)oximes 3a-n were synthesized for evaluating their human lipoprotein-associated phospholiphase A2 (Lp-PLA2) inhibitory activities. The less lipophilic derivatives 3a-c showed the most potent in vitro inhibitory activity on human Lp-PLA2.
Indium mediated allylation of glyoxylate oxime ethers, esters and cyanoformates

An indium mediated procedure has been developed for the allylation of activated O-functionalised oximes and nitriles as exemplified by a variety of glyoxylate derivatives. This method gives the corresponding free (or protected) amine in a one pot-process. The method is regiospecific and is carried out under remarkably mild conditions so that even oxime esters can be subjected to the typical reaction conditions.
