H makes a difference! A novel reactivity profile of propargyl vinyl ethers has been developed, which is controlled by the presence of a hydrogen atom at the homopropargylic position (see scheme; EWG=electron‐withdrawing group). This strategy was conveniently used to construct multifunctionalized phenolic platforms, including salicylaldehydes and the corresponding ketone derivatives.
H有所作为!已开发了炔丙基乙烯基醚的新型反应性谱,该分布是由在均炔丙基位置上存在氢原子控制的(请参见方案; EWG =吸电子基团)。该策略可方便地用于构建包括水杨醛和相应的酮衍生物在内的多功能酚平台。
