  Routes from 1,1-cycloalkanedicarboxylic acids to geminal bis(polyfluoromethyl) substituted carbocycles

  摘要：

  1-Fluoroformyl-1-1(trifluoromethyl)cycloalkanes (1), prepared by treatment of 1,1-cycloalkane-dicarboxylic acids with SF4, were efficiently reduced to 1-hydroxymethyl-1-(trifluoromethyl)-cycloalkanes (2). Routes for the conversion of alcohols 2 to 1-methyl-1-(trifluoromethyl) cycloalkanes (4), 1-fluoromethyl-1-(trifluoromethyl)cycloalkanes (6) and 1-difluoromethyl-1-(trifluoromethyl)cycloalkanes (8), via iodides 3, triflates 5 and aldehydes 7, respectively, were investigated.

• Nickel-Catalyzed Selective Reduction of Carboxylic Acids to Aldehydes

  The direct reduction of carboxylic acids to aldehydes is a fundamental transformation in organic synthesis. The combination of an air-stable Ni precatalyst, dimethyl dicarbonate as an activator, and silane reductant effects this reduction for a wide variety of substrates, including pharmaceutically relevant structures, in good yields and with no overreduction to alcohols. Moreover, this methodology

  将羧酸直接还原为醛是有机合成中的基本转变。空气稳定的Ni预催化剂，作为活化剂的二碳酸二甲酯和硅烷还原剂的结合可有效降低多种底物（包括药学上相关的结构）的收率，并且不会过度还原成醇。而且，该方法学是可扩展的，允许获得氘代醛，并且还与一锅使用醛产品兼容。
