Herein we report our results towards the total synthesis of (−)-dolabriferol, describing the synthesis of fragments C1–C9 and C10–C21. This convergent asymmetric approach relies on the use of a common Weinreb amide precursor for the preparation of both fragments, an efficient anti-aldol reaction followed by Zn(BH4)2 reduction to give a 1,3-syn diol, a selective oxidation of a triol under Swern conditions
在这里,我们报告了对(-)-二十碳四烯酚的全合成的结果,描述了片段C1-C9和C10-C21的合成。这种收敛的不对称方法依赖于使用常见的Weinreb酰胺前体来制备两个片段,有效的抗羟醛反应,然后还原Zn(BH 4)2以得到1,3-顺式二醇,选择性氧化在Swern条件下形成三醇并伴随形成乳醇,并用m -CPBA对烯丙基醇进行非对映选择性环氧化,然后用Me 2 CuCNLi 2有效地打开环氧化物。
