This invention is also related to uses of these compounds for lowering intraocular pressure, inhibiting cholesterol synthesis, relaxing lower urinary tract tissue, the treatment of begnin prostatic hyperplasia, impotency, cardiac arrythmia and for the treatment of any disease where the antagonism of the alpha 1A receptor may be useful. The invention further provides a pharmaceutical composition comprising a therapeutically effective amount of the above-defined compounds and a pharmaceutically acceptable carrier.
参考标题:Copper-Catalyzed One-Pot Synthesis Of Pyrimidines From Amides, N ,N ′-Dimethylformamide Dimethylacetal, And Enamines 作者:Hitesh B. Jalani,Wangshui Cai,Hongjian Lu |发布日期:2017.7.17 摘要:Versatile Copper Catalyzed One‐pot Synthesis Of Diversely Substituted Pyrimidines Directly From Amides, N,N′‐dimethylformamide Dimethylacetal (Dmf−dma) And Enamines Has Been Established. The Reaction Involved The Two C−n Bonds And One C−c Bond Formation By Formal [2+1+3] Annulation Approach To Pyrimidines. This Protocol Is Based On The Use Of Readily Available Primary Amides, Dmf−dma And Enamines To
