  Catalytic Enantioselective Hydrostannation of Cyclopropenes

  摘要：

  The first examples of catalytic enantioselective hydrostannation of the C=C double bond of cyclopropenes has been demonstrated. This method allows for the efficient synthesis of 2,2-disubstituted cyclopropylstannanes with high degrees of diastereo- and enantioselectivity. The facial selectivity of this reaction is entirely controlled by steric factors. A variety of functional groups at C-3 of the cyclopropenes were tolerated.

• Highly Diastereo- and Regioselective Transition Metal-Catalyzed Additions of Metal Hydrides and Bimetallic Species to Cyclopropenes:  Easy Access to Multisubstituted Cyclopropanes

  The first highly efficient, diastereo- and regioselective transition metal-catalyzed addition of metal hydrides (stannanes, silanes, and germanes) and bimetallic species (ditins and silyltins) to cyclopropenes has been developed. It was shown that the addition across the double bond of cyclopropenes is generally controlled by steric factors and proceeds from the least hindered face. This methodology

  已经开发出第一种高效的，非对映的和区域选择性的过渡金属催化的金属氢化物（锡烷，硅烷和锗烷）和双金属物质（二锡和甲硅烷基锡）添加到环丙烯中。结果表明，环丙烯双键的加成通常受空间因素控制，并且从受阻最小的面开始。这种方法论代表了一种针对各种高度取代的立体定义的环丙基金属的有力且原子经济的方法，而其他方法则无法提供有用的构建基块。
