摘要：

A practical method for the synthesis of oxindole-nitrones promoted by silica gel was developed with good results. The protocol is environmentally friendly as the reaction proceeds under solvent-free conditions with broad substrate scope, and high selectivity and chemical yield, and the silica gel can be quantitatively recovered and reused multiple times.
