We have demonstrated facile synthetic approach for some novel functionalized pyrazolo[4',3':5,6]pyrano[3,2-d]-[1,2]azaphospholes and pyrazolo[4',3':5,6]pyrano[2,3-d][1,3,2]diazaphosphinines via treatment of 6-amino-3-methyl-1,4-diphenyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile with some phosphorus halides. The structure of the products was characterized by elemental analysis and spectral tools. The antimicrobial and antioxidant activities of the products were also evaluated.
