  摘要：

  In the course of our study to find an ideal antihypertensive potassium channel opener (KCO), N-(2-cyanoethyl)-2,2 bis(fluoromethyl)-6-pentafluoroethyl-2H-1-benzopyran-4-carboxamide (13f, KC-515) showed a highly potent, slow and long-lasting antihypertensive effect with reduced reflex tachycardia, together with the beneficial effects of KCO such as improvement in lipid metabolism. These profiles identify KC-515 as a potential candidate. In conscious spontaneously hypertensive rats (SHR), the onset of the hypotensive effect of KC-515 (13f) was gradual and the maximum response was attained at around 6 h after dosing. The duration of action was over 18 h for 0.1 mg/kg. When administered to Zucker rats for 2 weeks with 0.03-0.3 mg/kg po range in the antihypertensive doses in hypertensive rat models, KC-515 (13f) significantly and dose-dependently reduced serum triglycerides to less than 70% of control without affecting total cholesterol.

  Starting, for example, from 1-fluoro-2-fluoromethyl-3-butyn-2-yl 4-trifluoromethylphenyl; ether, N-(2-cyanoethyl)-5-fluoro-4-fluoromethyl-4-(4-trifluoromethylphenoxy)-2-pentynamide is produced and then cyclized to synthesize 2,2-bis(fluoromethyl)-N-(2-cyanoethyl)-6-trifluoromethyl-2H-1-benzopyran-4-carboxamide. The invention processes for producing 4-substituted benzopyran derivatives involve fewer steps, feature greater safety and allow for easier purification than the prior art processes.
