established for the diversity‐oriented synthesis (DOS) of fused bi‐ and tricyclic systems containing benzannulated, 10‐ to 13‐membered chiral macrocycles embedded in carbohydrate templates. Macrocycles with different ring sizes have been prepared by pre‐designing the chiral building blocks. Base‐sensitive groups like acetyl and TBDPS survived the reaction conditions.
建立了基于无碱分子内Sonogashira反应的通用方法,用于融合双向和三环系统的多样性导向合成(DOS),该系统包含嵌入碳水化合物模板中的苯并环化的10至13元手性大环化合物。通过预先设计手性结构单元,可以制备出具有不同环尺寸的大环。碱敏感基团(例如乙酰基和TBDPS)在反应条件下仍然存在。
