[reaction: see text] The first total synthesis of (+/-)-trachyspic acid, a tumor cell heparanase inhibitor, was accomplished based on Cr(II)/Ni(II)-mediated reaction of the aldehyde containing the citric acid moiety and the long-chain triflate, and the relative configuration of this natural product was determined.
[反应:参见正文]基于Cr(II)/ Ni(II)介导的含柠檬酸部分的醛的反应,完成了肿瘤细胞乙酰肝素酶抑制剂(+/-)-曲奇酸的第一个全合成和长链三氟甲磺酸盐,并确定了这种天然产物的相对构型。
