  从动力学控制到热力学控制的变化使得邻二醇的反式选择性立体化学编辑成为可能

  摘要：

  在这里，我们报道了顺式-1,2-二醇选择性催化异构化为反式-双赤道-1,2-二醇。该方法采用三苯基硅烷硫醇（Ph 3 SiSH）作为催化剂，并在光氧化还原催化剂存在下和蓝光照射下在温和条件下进行。该方法具有高度化学选择性、广泛的官能团耐受性，并且提供了使用其他方法不易获得的反式二醇产物的简洁途径。机理研究表明，异构化是通过硅烷硫醇催化剂介导的可逆氢原子转移途径进行的。

  The invention relates to processes for preparing 3α-O-linked steroids including 3α-O-linked-androst-5-ene steroids and 3α-O-linked-5a-androstane steroids. In one process a 3α,4α-epoxy androst-5-en-17-one is predominately reduced at the epoxy moiety wherein reduction of the 3α,4α epoxy functional group occurs preferentially at position C4 with retention of configuration at position C3 to provide a 3α-O-linked-androst-5-ene steroid. In another process, conditions are provided for inversion of configuration of a 3β-hydroxy-androst-5-ene steroid by the Mitsunobu reaction to provide a 3α-O-linked-androst-5-ene steroid with reduced amounts of 3α,5α-cycloandrostane side-product impurities.

  该发明涉及制备3α-O-连接类固醇的过程，包括3α-O-连接-雄烯类固醇和3α-O-连接-5α-雄烷类固醇。在一个过程中，3α,4α-环氧基雄-5-烯-17-酮主要在环氧基团处还原，其中3α,4α-环氧官能团的还原优先发生在C4位置，并保留C3位置的构型，以提供3α-O-连接-雄烯类固醇。在另一个过程中，通过Mitsunobu反应提供条件，使3β-羟基雄-5-烯类固醇的构型发生倒置，以提供含有减少量3α,5α-环雄烷副产物杂质的3α-O-连接-雄烯类固醇。

The use of other ionic liquids/molten salts resulted in a decrease in the conversion and/or in reduced selectivity. In [bmim]+Br-, a conversion of 2,3-epoxy-17-ones into 2,17- and 3,17-diones was also observed. catalysis - epoxides - ionic liquids - ring-opening - steroids - thiols

  Efficient ring opening of steroidal 2,3-epoxides with stoichiometric amount of aromatic amines has been carried out using an ionic liquid ([bmim](+)[BF4](-)) both as solvent and catalyst. The reactions were completely regio- and stereoselective in each case. The aminoalcohol products have chair conformations in ring A. The ionic liquid-mediated ring opening can efficiently be carried out with aliphatic amines like morpholine as well. (c) 2006 Elsevier Inc. All rights reserved.
