Rhodium(iii)-catalyzed aromatic C-H cyanation with dimethylmalononitrile as a cyanating agent

A rhodium-catalyzed aromatic C-H bond direct cyanation with safe, bench-stable, and commercially available dimethylmalononitrile as the cyanating agent has been successfully developed by using copper oxide as a promotor. Pyridine, quinoline, pyrimidine and pyrazole were used as the directing group in this type of C-H bond direct cyanation reaction.

Pyridopyrimidine Angiotensin II Antagonists

A series of pyridopyrimidine angiotensin II (A II) antagonists was synthesized and tested for antagonism of A II. Compounds with a biphenyltetrazole pharmacophore and small alkyl groups at the 2- and 4-positions of the pyridopyrimidine ring were found to be the most potent in an AT1 receptor binding assay and in blocking the A II pressor response in anesthetized, ganglion-blocked A II-infused rats. 5,8-Dihydro-2,4-dimethyl-8--4-yl)methyl>pyridopyrimidin-7(6H)-one (4a) was one of the more potent compounds in the binding assay and was the most efficacious compound in the A II-infused rat model. Further study of 4a in Goldblatt (2K-1C) rats showed the compound to have oral bioavailability and to be an efficacious and potent compound in a high renin form of hypertension.

SUBSTITUTED BENZIMIDAZOLES AND QUINAZOLINES AS ANTIHYPERTENSIVES

There are disclosed compounds of the formula STR1 wherein R 1 is STR2 R 2 is STR3 wherein X is STR4 wherein R. sup.5 is hydrogen, alkyl of 1-6 carbon atoms, benzyl, triphenylmethyl, or Sn(alkyl of 1-6 carbon atoms) 3 ;n is 1 to 3;Y is STR5 wherein R 3 is hydrogen, perfluoro alkyl of 1-6 carbon atoms, trifluoromethylalkyl of 1-6 carbon atoms, or alkyl of 1-6 carbon atoms; and R 4 is hydrogen or alkyl of 1-6 carbon atoms; with the proviso that when R 1 is STR6 then R. sup.2 cannot be STR7 wherein X is as defined above; and the pharmaceutically acceptable salts thereof, which by virtue of their ability to antagonize angiotensin II are useful for the treatment of hypertension and congestive heart-failure.

SUBSTITUTED PYRROLOPYRIMIDINES, AZEPINOPYRIMIDINES AND PYRIDOPYRIMIDINES USEFUL AS ANGIOTENSIN II ANTAGONISTS

This invention relates to pyrrolo-, pyrido-, azepino-, and azocinopyrimidines of the general formula I STR1 wherein R 1, R. sup.2, R 3, and R 4 are independently H, lower alkyl containing 1 to 6 carbon atoms, or perfluoroalkyl containing 1 to 6 carbon atoms; R. sup.5 is H or when n is 1 R 5 taken together with R 3 comprises a double bond; n is 0 to 1; p is 0 to 2; m is 0 to 3; Ar 1 is STR2 wherein W is H, lower alkyl containing 1 to 6 carbon atoms, halogen, hydroxy, or lower alkoxy containing 1 to 6 carbon atoms; Ar 2 is STR3 wherein X is STR4 wherein R. sup.6 is H, tert-butyl, tri-n-butylstannyl, or triphenylmethyl; and the pharmaceutically acceptable salts thereof which by virtue of their ability to antagonize angiotensin II are useful for the treatment of hypertension, congestive heart failure, and restenosis.
