    摘要:
    利用固态酸和碱进行环氧化物与Me3SiCN开环反应的新尝试已被研究。与均相催化剂相比,固态强碱如氧化钙和氧化镁能更有效地催化环氧化物与Me3SiCN的区域选择性和化学选择性开环反应。在氧化钙和氧化镁存在下,不对称环氧化物与Me3SiCN的反应通过氰离子对次级环氧碳的区域和立体选择性攻击,高产率地生成了3-三甲基硅氧基烷腈。此外,在氧化钙存在下,2,3-环氧-1-醇衍生物被氰离子选择性地转化为相应的C-3开环产物,且未形成异氰化物。研究提出,氧化钙作为一种双功能催化剂,其晶格氧化物阴离子活化Me3SiCN,同时钙离子作为路易斯酸位点促进环氧醇的开环反应。

  • Regiochemical control of the ring opening of 1,2-epoxides by means of chelating processes. 5. Synthesis and reactions of some 2,3-epoxy-1-alkanol derivatives

    In order to study the effect of a remote polar functionality on the regiochemistry of the ring opening of aliphatic epoxides, the synthesis and some nucleophilic additions (methanolysis, azidolysis, and aminolysis) of suitable 2,3-epoxy-1-alkanol derivatives (epoxides trans-1a-d and cis-2) were carried out. The C-3 selectivity commonly observed when nonchelating ring opening conditions are used is lower than when the epoxides are allowed to react in the presence of metal ions (Li+, Mg2+, Zn2+) due to the probable intervention of bidentate-chelated intermediates in the latter case, and in some instances an almost complete C-3 regioselection is obtained. Under identical conditions involving chelation control, trans epoxide la shows higher C-3 selectivity than cis isomer 2. A free hydroxyl functionality is not necessary in order to observe chelation-controlled regioselectivity in the epoxides that we examined.

    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.

  • Regiospecific Ring Opening of Epoxides with Cyanotrimethylsilane on Solid Bases: Reaction Features, and Role of Metal Cations of Solid Bases

    A new attempt of utilizing solid acids and bases for ring opening of epoxides with Me3SiCN was investigated. Solid strong bases such as calcium oxide and magnesium oxide catalyzed the regio- and chemoselective ring opening of epoxides with Me3SiCN much more effectively than homogeneous catalysts. On CaO and MgO, the reactions of unsymmetrical epoxides with Me3SiCN afforded 3-trimethylsiloxyalkanenitriles in high yields through regio- and stereoselective attack of cyanide ion on the less substituted epoxycarbon. Additionally, on CaO, 2,3-epoxy-1-alkanol derivatives were selectively converted to the corresponding C-3 opened products by the attack of cyanide ion. In these cases no isocyanides were formed. It was suggested that CaO acted as a bifunctional catalyst; the lattice oxide anions of CaO activated Me3SiCN, and simultaneously calcium ions promoted the ring opening of epoxyalkanol as Lewis acid sites.
