Convenient syntheses of relatively rare 2,2-disubstituted-2,3-dihydro~l,4-benzodioxins from 2-substituted-2-hydroxy-2,3-dihydro-l,4-benzodioxins, as key synthetic intermediates, are reported. These new synthetic approaches require Lewis acid BF3-Et20 mediated nucleophilic substitution reaction or cy
