Triisopropyl borate effects the condensation of aldehydes with sulfinamides to give N-sulfinyl imines. The reaction is amenable to 1°, 2°, and 3° alkyl aldehydes, as well as aryl, heteroaryl, and α,β-unsaturated aldehydes. In addition to tert-butanesulfinamide, the condensation is also effective with 4-toluenesulfinamide and 2,4,6-triisopropylphenylsulfinamide. This protocol proceeds under homogeneous
硼酸三异丙酯使醛与亚磺酰胺缩合,生成N-亚磺酰基亚胺。该反应适合于1°,2°和3°烷基醛,以及芳基,杂芳基和α,β-不饱和醛。除叔丁烷亚磺酰胺外,缩合反应还与4-甲苯亚磺酰胺和2,4,6-三异丙基苯基亚磺酰胺有效。该方案在均相反应条件下进行,不需要不溶试剂或副产物的反应后过滤。
