γ-Acyl- and related δ-lactones having no 6 substituents were synthesized in a sequence of reactions, 1,4-conjugate additions of sulfurstabilized acetate anions to α,β-unsaturated ketones, followed by trapping of the resultant ketone enolates with formaldehyde, mild lactonization, and desulfurization.
在一系列反应中合成了没有 6 个取代基的 γ-酰基-和相关的 δ-内酯,硫稳定的乙酸根阴离子与 α,β-不饱和酮的 1,4-共轭加成,然后用甲醛捕获生成的酮烯醇化物,温和内酯化、脱硫。
