A new mild method has been devised for generating o-(naphtho)quinone methides via fluoride-induced desilylation of silyl derivatives of o-hydroxybenzyl(or 1-naphthylmethyl) nitrate. The reactive o-(naphtho)quinone methide intermediates were trapped by C, O, N and S nucleophiles and underwent “inverse electron-demand” hetero Diels- Alder reaction with dienophiles to give stable adducts. The method has useful potential application in natural product synthesis and drug research
