Synthesizing the synthons: The development of α‐acylvinyl anion synthons has been achieved using direct α‐vinyl enolization of α,β‐unsaturated ketones under mild reaction conditions. The synthetic utility of such synthons has been demonstrated in intermolecular aldol and aldol condensation reactions, which provide synthetically useful allenyl ketone and enyne derivatives.
合成子的合成:在温和的反应条件下,通过α,β-不饱和酮的直接α-乙烯基烯化作用,已经实现了α-酰基乙烯基阴离子合成子的开发。此类合成子的合成效用已在分子间的醇醛和醇醛缩合反应中得到证明,其提供了合成上有用的烯丙基酮和烯炔衍生物。
