An oxidant-free Rh(III)-catalyzeddirect amidation of alkyl dithianes via C(sp3)–H bond activation utilizing diverse and robust dioxazolone reagents is reported. The reaction hinges on use of a Cp*Rh(III) complex in combination with an essential amino-carboxylate additive to generate usefully protected 1,3-aminoaldehyde derivatives. The scalability of the reaction was demonstrated as was a series of
据报道,利用多种稳定的二恶唑酮试剂,通过C(sp 3 )–H 键活化,在无氧化剂 Rh( III ) 催化下,烷基二噻烷直接酰胺化。该反应取决于使用 Cp*Rh( III ) 络合物与必需的氨基羧酸盐添加剂组合来生成有效保护的 1,3-氨基醛衍生物。反应的可扩展性以及一系列下游产物功能化(包括二噻烷脱保护、阴离子烷基化和还原脱硫)得到了证明,突出了这种转化在新型支架和结构单元合成中的普遍适用性。
