Starting from β-oxodithioesters and hydroxylamine, two completely different transformations afford either β-ketonitriles or isoxazoles with high chemoselectivity depending on the reaction conditions. The reaction of β-oxodithioesters with hydroxylamine in EtOH at room temperature in daylight gave β-ketonitriles in high yields. On the other hand, 3-methylthio-isoxazoles were efficiently obtained as the final products by heating the mixture of β-oxodithioesters and hydroxylamine in HOAc at 90 °C.

Described herein is design, synthesis, and biological evaluation of novel series of 2-aryl-7-(3′,4′-dialkoxyphenyl)-pyrazolo[1,5-a]pyrimidines acting as inhibitors of type 4 phosphodiesterase (PDE4) which is known as a good target for the treatment of asthma and COPD. For this purpose, structure optimization was conducted with the aid of structure-based drug design using the known X-ray crystallography. Also, biological effects of these compounds on the target enzyme were evaluated by using in vitro assays, leading to the potent and selective PDE-4 inhibitor (IC50 10 nM).
