(4R,15R,16R,21S)-Rollicosin (2) was synthesized by palladium-catalyzed coupling of two building blocks 4 and 5. Lactone 4 was synthesized from 1-heptyne and terminal acetylene 5 was prepared from lactone 6 and allyl iodide or (S)-epichlorohydrin. (4S,15R,16R,21S)-Rollicosin (3) was also synthesized from (R)-epichlorohydrin by the same synthetic pathway.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim
(4R,15R,16R,21S)-Rollicosin (2) 通过钯催化偶联两个结构单元 4 和 5 合成。内酯 4 由 1-庚炔合成,末端乙炔 5 由内酯 6 和烯丙基碘或(S)-表氯醇。(4S,15R,16R,21S)-Rollicosin (3) 也由 (R)-表氯醇通过相同的合成途径合成。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
