of a method for addition of trimethylsilyl cyanide to chiral oxazolidinone-derived N-acylhydrazones is described. The diastereoselectivity was found to be highly dependent on the substituent of the oxazolidinone moiety; 4-phenyl-2-oxazolidinone achieved much higher stereocontrol than four other oxazolidinones screened. The reaction gives modest selectivity with aliphatic hydrazones and excellent selectivity
描述了将氰化三甲基硅烷添加到手性恶唑烷酮衍生的 N-酰基腙中的方法的开发。发现非对映选择性高度依赖于恶唑烷酮部分的取代基;与筛选的其他四种恶唑烷酮相比,4-苯基-2-恶唑烷酮实现了更高的立体控制。该反应对脂肪族腙具有适度的选择性,而对由芳族醛制备的腙具有优异的选择性。
