Li2PdCl4 and 3-butenoic or 4-pentenoic acids, followed by refluxing with K2CO3, affords high yields of the corresponding γ-alkenyl-γ-butyro- or δ-alkenyl-δ-valerolactones by an intramolecular π-allylpalladium displacement process.
乙烯基汞氯化物,Li 2 PdCl 4和3-丁烯酸或4-戊烯酸的反应,然后与K 2 CO 3回流,得到相应的γ-烯基-γ-丁丁-或δ-烯基-δ-的高产率。戊内酯通过分子内π-烯丙基钯置换工艺制备。
