Abstract Pinolide, a naturally occurring nonenolide and its C2 epimer have been synthesized using d-mannitol and 1,2-epoxyhex-5-ene as the starting materials. The synthesis involves the Jacobsen’s hydrolytic kinetic resolution, Yamaguchi esterification, and intramolecular ring-closing metathesis as the key steps. The 2-epi-pinolide, the C2 epimer of pinolide, has been synthesized for the first time. The
摘要 吡喃内酯,一种天然存在的壬烯内酯及其C2差向异构体已使用d-甘露糖醇和1,2-环氧己基-5-烯作为起始原料合成。合成涉及关键步骤,包括雅各布森的水解动力学拆分,山口酯化和分子内闭环复分解。己内酰胺的C2差向异构体2- epi- pinolide首次合成。已经研究了披尼洛德和2-表-披尼洛德的细胞毒活性。 吡喃内酯,一种天然存在的壬烯内酯及其C2差向异构体已使用d-甘露糖醇和1,2-环氧己基-5-烯作为起始原料合成。合成涉及关键步骤,包括雅各布森的水解动力学拆分,山口酯化和分子内闭环复分解。己内酰胺的C2差向异构体2- epi- pinolide首次合成。已经研究了披尼洛德和2-表-披尼洛德的细胞毒活性。
