  Total Synthesis of CRM646-A and -B, Two Fungal Glucuronides with Potent Heparinase Inhibition Activities

  摘要：

  CRM646-A (1) and -B (2), two fungal glucuronides with a dimeric 2,4-dihydroxy-6-alkylbenzoic acid (orcinolp-depside) aglycone showing significant heparinase and telomerase inhibition activities, were synthesized for the first time. The successful approach involved construction of the phenol glucuronidic linkage, via coupling of the orsellinate derivative 27 with glucuronate bromide 7, before assembly of the phenolic ester linkage in the depside aglycone. Attempts via direct glycosylation of the depside aglycone derivatives were not successful.
