A simple and environmentally friendly method to synthesize spiropyrazolo[3,4-b]pyridines derivatives starting from isatin, cyclic-1,3-diketone and 3-methyl-5-aminopyrazole was developed. With the optimized conditions for enzymes, solvents, enzyme loading and reaction time in hand, 9 compounds were obtained in acceptable yields. Moreover, the investigation in fluorescent properties of these products showed their potential application in the field of new fluorescent material. (C) 2017 Elsevier Ltd. All rights reserved.
