A series of benzo‐macrolactones has been prepared by chemical synthesis, and evaluated as inhibitors of heat shock protein 90 (Hsp90), an emerging attractive target for novel cancer therapeutic agents. A new synthesis of these resorcylic acid macrolactone analogues of the natural product radicicol is described in which the key steps are the acylation and ring opening of a homophthalic anhydride to
已经通过化学合成制备了一系列的苯并马甲内酯,并被评估为热休克蛋白90(Hsp90)的抑制剂,HSP90是新型癌症治疗剂的新兴靶标。描述了天然产物radicicol的这些间苯二酸大内酯类似物的新合成,其中关键步骤是酰化和开裂高邻苯二甲酸酐以生成异香豆素,然后进行开环易位以形成大环。该方法已扩展到一系列新的结合了1,2,3-三唑环的内酯。
