Abstract
Abstract Convenient syntheses of relatively rare 2,2-disubstituted-2,3-dihydro-1,4-benzodioxins from 2-substituted-2-hydroxy-2,3-dihydro-1,4-benzodioxins, as key synthetic intermediates, are reported. These new synthetic approaches require Lewis acid BF3-Et2O mediated nucleophilic substitution reaction or cyclization of suitable hydroxyphenols.
