  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.

  Copper-Catalyzed Double C–S Bonds Formation via Different Paths: Synthesis of Benzothiazoles from N-Benzyl-2-iodoaniline and Potassium Sulfide

  摘要：

  A new, highly efficient procedure for the synthesis of benzothiazoles from easily available N-benzyl-2-iodoaniline and potassium sulfide has been developed. The results show copper-catalyzed double C-S bond formation via a traditional cross-coupling reaction and an oxidative cross-coupling reaction.

  日期：2014.8.15

  An organocatalytic protocol for the syntheses of 2-substituted benzoxazoles and benzothiazoles is described from alkyl-/arylanilides and alkyl-/arylthioanilides using 1-iodo-4-nitrobenzene as catalyst and oxone as an inexpensive and environmentally safe terminal oxidant at room temperature in air via oxidative C-H functionalization and C-O/S bond formation. The procedure is simple and general and provides an effective route for the construction of functionalized 2-alkyl-/arylbenzoxazoles and 2-alkyl-/arylbenzothiazoles with moderate to high yields. The synthetic and mechanistic aspects have been described.
