(-)-Neocnidilide (1), an antifungal substance isolated from Cnidium officinale Makino and its antipode 11 were respectively synthesized from (S)- and (R)-(E)- 1-ethenylpentyl 2, 4-pentadienoate (4) and (5) via the intramolecular Diels-Alder reaction. This synthesis established that the absolute configuration of 1 was 3S, 3aR.
通过分子内 Diels-Alder 反应,分别从(S)-和(R)-(E)-1-乙烯基戊基 2,4-戊二烯酸酯(4)和(5)合成了从 Cnidium officinale Makino 分离出来的抗真菌物质 (-)-Neocnidilide (1)及其抗生素 11。这一合成确定了 1 的绝对构型为 3S、3aR。
