The one-pot synthesis of azide-substituted dihydropyrazoles in isopropanol was successfully achieved, followed by investigation of Staudinger-aza-Wittig-dehydroaromatization reactions with methyl(diphenyl)phosphine for further application in the construction of pyrazolo[1,5- c ]quinazolines.
The one-pot synthesis of azide-substituted dihydropyrazoles in isopropanol was performed by using chalcones, hydrazine hydrate, and an acyl chloride at 0 celcius. Subsequent Staudinger-aza-Wittig-dehydroaromatization reactions of the products with methyl(diphenyl)phosphine were also investigated for further application in the construction of pyrazolo[1,5- c ]quinazolines.
