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
已经设计了一种新的温和的方法,用于通过氟化物诱导邻羟基苄基(或1-萘甲基)硝酸酯的甲硅烷基衍生物的甲硅烷基化来生成邻(萘)醌甲基化物。反应性邻-(萘)醌甲基化物中间体被C,O,N和S亲核试剂俘获,并与亲二烯体进行“反电子需求”异Diels-Alder反应,得到稳定的加合物。该方法在天然产物合成和药物研究中具有潜在的潜在应用价值。
