bond cleavage, with formation of 3-amino-2,1-benzisoxazole derivatives (3). The leaving phosphorus moiety was identified here as phosphoric acid. In the case of basic hydrolysis of corresponding esters, new cyclic phosphorus compounds (derivatives of benzoxazaphosphorin-3,1,2 Pv-one-2) were obtained. The cyclic products were formed as a result of the subsequent reaction of anthranil derivatives with
