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.
一种新的温和方法已经被设计出来,用于通过氟化物诱导的 o-羟基苄基(或 1-萘甲基)硝酸盐的硅基衍生物的去硅化来生成 o-(萘并)醌甲叉。反应性的 o-(萘并)醌甲叉中间体被 C、O、N 和 S 亲核试剂捕获,并与亲二烯体发生“反向电子需求”杂 Diels-Alder 反应,生成稳定的加合物。该方法在天然产物合成和药物研究中有有用的潜在应用。
