  Stereospecific Formation of Optically Active 5-Alkyl-4-methyl-3-[(trialkylsilyl)oxy]-2-([(trialkylsilyl)oxy]- methyl)tetrahydrofurans via Diastereoselective Epoxidation and Rearrangement of 5-[(Trialkylsilyl)oxy]-2-alken-1-ols¹

  摘要：

  A novel method for the synthesis of a series of silyl ethers of 3-(silyloxy)tetrahydrofuran-2-methanols bearing substituents at all four carbon atoms of the ring has been developed. The process involves first non-aldol aldol reaction of the epoxy silyl ether 8 to give the anti aldol product 9, stereoselective olefination and reduction to the (E)- and (Z)-allylic alcohols 10 and 11, diastereoselective epoxidation of these alcohols to give any of the four diastereomeric epoxy alcohols 12-15, silylation of the alcohols to give the epoxy silyl ethers 27-30, and final Lewis acid catalyzed rearrangement of the epoxy silyl ethers to give the desired products 31-33 and 36. In the first three instances, good yields of the desired 3-(silyloxy)-2-((silyloxy)methyl)tetrahydrofurans were obtained. However, rearrangement of the epoxy silyl ether 27 gave a mixture of products, the bis-silyl ether 36 as well as the products of a second non-aldol aldol process. This hydride migration to give the 3,5-bis((trialkylsilyl)oxy)-2,4-dimethylalkanal 35 or its internally protected 1-(silyloxy)pyran 38 can be made to occur in good yield.

  In our study of the total synthesis of (+)-irciniastatin A, we found a need to develop a method that enables a C3-selective nucleophilic ring opening of 2,3-epoxy alcohol by MeOH, by which we found that the use of combined catalytic amounts of Eu(OTf)3 and 2,6-di-tert-butyl-4-methylpyridine (DTBMP) enables the intended transformation to obtain 3-methoxy-1,2-diol efficiently. Promising features of a

  在我们对（+）-irciniastatin A的总合成的研究中，我们发现有必要开发一种方法，该方法能够使MeOH对2,3-环氧醇进行C3选择性亲核开环，从而发现使用Eu（OTf）3和2,6-二叔丁基-4-甲基吡啶（DTBMP）的组合催化量能够实现预期的转化，从而有效地获得3-甲氧基-1,2-二醇。描述了使用包括醇，硫醇和未保护的胺在内的各种亲核试剂实现2,3-和3,4-环氧醇的高度区域选择性亲核开环的方案的有前景的特征。
