via C–C and C–O bond formation has been achieved with electron rich aromatic groups and vinylogous esters acting as independent nucleophiles. The reaction provides oxabicyclo[3.2.1]octanes and [4.2.1]nonanes from commercially available 3-alkoxy cycohexen-2-ones in three steps.
碘化苯通过C–C和C–O键形成的1,2-烯烃官能化已通过富电子芳族基团和乙烯基酯作为独立亲核试剂实现。该反应通过三个步骤从商购的3-烷氧基环己烯-2-酮提供氧杂双环[3.2.1]辛烷和[4.2.1]壬烷。
