Novel imidazole derivatives of the general formula (I): ##STR1## wherein Y is a carboxyl group, an alkoxycarbonyl group, a cyano group, a hydroxymethyl group, an aminomethyl group, a formyl group or a carbamoyl group, and A and B, which may be the same or different, each is a straight- or branched-chain alkylene or alkenylene group, and n and m, which may be the same or different, each is zero or 1, with the proviso that when A is methylene group or n is zero, m is 1; and pharmaceutically acceptable salts thereof. These compounds have a strong inhibitory effect on thromboxane synthetase from rabbit platelet microsomes, and are useful as therapeutically active agents for the treatment of inflammation, hypertension, thrombus, cerebral apoplexy and asthma.

A general and practical protocol is presented for visible-light-driven deoxygenativecoupling of alcohols with aromatic nitriles in the absence of external photocatalysts. Utilizing a hydroxyl activation strategy with carbon disulfide, this C(sp3)–C(sp2) constructing platform accommodates a broad scope of alcohols and aryl nitriles to deliver various alkyl-substituted arenes. Mechanism studies show
