in a concise way, thereby elucidating the relative stereochemistry of the aryl and carboxylicacid groups in 1a. The synthesis employed selective monohydrolysis of the dilactones derived from oxidative dimerization of cinnamic acid derivatives. This approach provided a practical synthetic route to α‐arylidene‐γ‐lactones.
摘要 以简洁的方式制备了Phellinsin A (1a),从而阐明了1a 中芳基和羧酸基团的相对立体化学。该合成采用了源自肉桂酸衍生物氧化二聚化的双内酯的选择性单水解。该方法为α-亚芳基-γ-内酯的合成提供了一条实用的途径。
