Benzisoxazole is a critical subunit in pharmaceuticals with important biological and pharmaceutical activities,1 including antipsychrotic,antitumor,antimicrobial and ehrolinesterase-inhibiting(Alzheimers disease) properties.Traditional method2 of synthesis of benzisoxazole is a 3-4 steps synthesis which in some cases needs strongly acidic condition reaction and in other cases requires the use of strong base,like organometallics.The idea of using [3+2] cycloaddition reaction to form benzisoxazole has been reported,but our condition is more environmental friendly.
