new scaffolds with taxol-eleutherobin hybrid core structures and a taxol-sugar hybrid. The synthesis of taxol-eleutherobin hybrids involved the synthesis of the A-ring fragment from carvone and the C-ring fragment from either D-mannose or D-glucose. The Shapiro reaction was used as the key reaction to couple the A- and C-ring fragments of these hybrid structures. Unfortunately, another key reaction
本文描述了我们在合成具有紫杉醇-eleutherobin 混合核心结构和紫杉醇-糖混合结构的新型支架方面的设计和努力。紫杉醇-eleutherobin 杂合体的合成包括合成来自香芹酮的 A 环片段和来自 D-甘露糖或 D-葡萄糖的 C 环片段。Shapiro 反应被用作偶联这些杂化结构的 A 环和 C 环片段的关键反应。不幸的是,另一个关键反应 (RCM) 未能形成 B 环和本质上的核心单元。然而,串联烯炔交叉复分解/分子内 Diels-Alder 策略用于合成类群-氧杂-糖杂化物。
