摘要

A microwave-assisted, fluorous synthetic route to< AQ verify> 3-amino-1, 2-benzisoxazoles and 4-amino-1H-2, 3-benzoxazines has been developed. The strategy comprises linking the respective 2-fluorobenzonitrile or 2-(bromomethyl) benzonitrile to a fluorous oxime tag to give an aryloxime intermediate which then undergoes cyclization with concomitant cleavage of the substrate-tag in acidic conditions to provide the desired product in good to moderate ...
