A microwave-mediated synthesis of 1H-pyrazole-5-amines utilizing 1 M HCl at 150 °C was developed in order to provide products in a matter of minutes with minimal purification. Most reactions are complete in only 10 min and can be isolated via a simple filtration without the need for further purification by column chromatography or recrystallization. This method tolerates a range of functional groups and can be performed on milligram to gram scales.

A highly effective hydroxylation reaction of aryl halides with water under synergistic organophotoredox and nickel catalysis is reported. The OH group of the resulting phenols originates from water, following deprotonation facilitated by an intramolecular base group on the ligand. Significantly, aryl bromides as well as less reactive aryl chlorides served as effective substrates to afford phenols with a wide range of functional groups. Without the need for a strong inorganic base or an expensive noble-metal catalyst, this process can be applied to the efficient preparation of diverse phenols and enables the hydroxylation of multifunctional pharmaceutically relevant aryl halides.

Benzoylacetonitrile and β-aminocinnamonitrile are shown to possess potent intiinflammatory activity in the rat adjuvant arthritis model. In a series of phenyl-substituted analogues, only o-, m-, and p-fluorobenzoylacetonitrile and m- and p-fluoro-β-aminocinnamonitrile retained activity. Additionally, β-amino-2- and β-amino-3-thiopheneacrylonitrile and β-oxo-2- and β-oxo-3-thiophenepropionitrile exhibited similar activity. These agents are not believed to be acting via prostaglandin synthetase inhibition. The metabolic profile of benzoylacetonitrile is also described.

Novel 4-2,3 or 4(3-amino-2-hydroxypropoxy) phenyl!-and 5-2, 3 or 4(3-amino-2-hydroxypropoxy) phenyl!-1,2,3-thiadiazole derivatives which may be further substituted at the C-5 or C-4 position of the thiadiazole ring, respectively, by a lower alkyl, phenyl, trifluoromethyl, carboxy, alkoxycarbonyl, cyano or an aminocarbonyl group, and the pharmaceutically acceptable acid addition salts thereof and processes for the production of such compounds; 4-4(3-t-butylamino-2-hydroxypropoxy) phenyl!-1,2,3-thiadiazole and 5-4(3-t-butylamino-2-hydroxypropoxy) phenyl!-1,2,3-thiadiazole are representative of the class. These compounds possess cardiovascular activity and are useful for the treatment of abnormal heart conditions in mammals.
