Uno, Hitoshi; Kurokawa, Mikio published the artcile< Studies on 3-substituted 1,2-benzisoxazole derivatives. IV. Rearrangement of N-substituted 2H-1,2-benzisoxazolin-3-one to 2-substituted 2H-1,3-benzoxazin-4-one>, Recommanded Product: Benzo[d]isoxazol-3-ol, the main research area is benzoxazinone; benzisoxazolinone ring expansion rearrangement; alkylation hydroxybenzisoxazole.
The base catalyzed ring expansion of 2-substituted 2H-1,2-benzisoxazolin-3-ones I (R = Ph, CO2Me, COPh, COMe, CCH, R1 = H; R = R1 = Ph; R = CO2Et, R1 = Me) to 2-substituted 2H-1,3-benzoxazin-4-ones II occurred during the alkylation of hydroxy-1,2-benzisoxazole.
Chemical & Pharmaceutical Bulletin published new progress about Rearrangement. 21725-69-9 belongs to class isoxazole, and the molecular formula is C7H5NO2, Recommanded Product: Benzo[d]isoxazol-3-ol.
