Van Eker, Daniel; Chauhan, Jay; Murphy, William A.; Conlon, Ivie L.; Fletcher, Steven published the artcile< Chromatography-free, Mitsunobu-triggered heterocyclizations of salicylhydroxamic acids to 3-hydroxybenzisoxazoles>, Quality Control of 21725-69-9, the main research area is hydroxybenzisoxazole preparation; salicylhydroxamic acid heterocyclization Mitsunobu.
A swift and efficient preparation of 3-hydroxybenzisoxazoles I (R = H, 6-F, 6-Cl, 7-OCH3, 5-NO2, etc.) by the Mitsunobu-triggered heterocyclizations of salicylhydroxamic acids, which can be isolated by an acid-base work-up was reported. As expected, a range of functional groups was compatible with the chem.
Tetrahedron Letterspublished new progress about Heterocyclization. 21725-69-9 belongs to class isoxazole, and the molecular formula is C7H5NO2, Quality Control of 21725-69-9.
