reaction of 3,4-pentadien-2-one, iodide ion, and aldehydes in the presence of ZrCl4 as the catalyst gave the 3-iodohomoallylic alcohols in good yields, which could be further transformed to α,β-unsaturated γ-lactones by palladium-catalysed cyclocarbonylation.
在ZrCl 4作为催化剂的情况下,3,4-戊二烯-2-酮,碘离子和醛类的串联亲核加成-醛醇反应以良好的收率得到了3-碘代高代烯丙基醇,可以进一步转化为α,钯催化的环羰基化反应生成的β-不饱和γ-内酯。
