摘要
树豆酮酸B显示出良好的过氧化物酶体增生物激活受体γ拮抗活性,具有潜在抗糖尿病的生物活性。以4-甲氧基水杨酸甲酯为起始原料,经Williamson醚化、O[1,3]迁移和Claisen重排一锅反应、酚羟基甲基化保护、酯水解、C—H活化/环合级联反应、选择性脱甲基、水解6步反应合成树豆酮酸B,总收率为18.2%,化合物结构经^(1)HNMR、^(13)CNMR和ESI-HRMS表征,与目标产物相符。报道树豆酮酸B的全合成路线,为树豆酮酸B的开发应用奠定了基础。
Cajanonic acid B exhibites good antagonistic activity on peroxisome proliferator activated receptor γ and has potential anti diabetic biological activity.Cajanonic acid B was synthesized from methyl 4-methoxysalicylate via one pot reaction of Williamson etherification, O[1,3]-Migration and Claisen rearrangement, hydroxy protection, ester hydrolysis, C—H activation/annulation cascade reactions, selective demethylation, and hydrolysis with an overall yield of 18.2%.The chemical structure of synthesized compound was confirmed by ^(1)HNMR,^(13)CNMR and ESI-HRMS,consistenting with the target product.The synthetic route of cajanonic acid B was reported, and laided a foundation for the development and application of cajanonic acid B.
