Organic phosphorus compounds. 1. 4-(Benzothiazol-2-yl)benzylphosphonate as potent calcium antagonistic vasodilator
摘要:
A series of 4-(benzothiazol-2-yl)benzylphosphonic acid dialkyl ester derivatives were synthesized and evaluated for coronary vasodilatory activity by Langendorff's method in the isolated guinea pig heart. Many of the phosphonic acid dialkyl esters exhibited vasodilatory activity and calcium antagonism comparable with those of diltiazem hydrochloride, whereas phosphonic acid 1b and its nonphosphonated precursor 7a were inactive. These results indicate the necessity of the diethoxyphosphinyl moiety for vasodilatory activity. Substitution of the benzothiazole ring with a variety of substituents did not significantly enhance the activity of the unsubstituted compound. Compound 10b (KB-944) was chosen for detailed pharmacological evaluation.

A one-potthree-component tandem reaction involving a key Pictet-Spengler-like annulation step has been developed, providing an efficient method for the synthesis of 3,4-dihydroquinazolines in moderate to good yields from amides, aldehydes, and amines. The multicomponent triflic anhydride mediated reaction tolerates the installation of numerous functional groups, affording extensive diversity about

A binaphthyl‐supported Pd nanoparticles (Pd‐BNP)‐catalyzed aminocarbonylation of aryliodides in the presence of carbon monoxide and amines for the synthesis of amides has been developed. This methodology provides an efficient route for the synthesis of a COX‐2 enzyme inhibitor having anti‐inflammatory activity.
