Various α,β-unsaturated carbonylcompounds, such as α,β-unsaturated esters, α,β-unsaturated ketones, α,β-unsaturated nitriles, and α,β-unsaturated amides, were directly converted to the corresponding a-hydroxyimino carbonylcompounds in high yields on treatment with butyl nitrite and phenylsilane in the presence of a catalytic amount of N,N′-bis(2-ethoxycarbonyl-3-oxobutylidene)ethylenediaminatocobalt(II)
α,β-不饱和酯、α,β-不饱和酮、α,β-不饱和腈、α,β-不饱和酰胺等多种α,β-不饱和羰基化合物直接转化为相应的α-羟基亚氨基羰基在温和条件下,在催化量的 N,N'-双(2-乙氧基羰基-3-氧代丁二烯)乙二氨基钴 (II) 配合物存在下,用亚硝酸丁酯和苯基硅烷处理高产率的化合物。

Rh(III)-Catalyzed C–H Activation and [4+1+1] Sequential Cyclization Cascade to Give Highly Fused Indano[1,2-<i>b</i>]azirines
developed to construct the highly fused indano[1,2-b]azirine frameworks in good yields with a broad range of substrates under mild reaction conditions. More intriguingly, a [4+1+1] sequential annulation cascade is demonstrated for the first time in this reaction and opened a new reaction mode for α-keto oximes. These fused indano[1,2-b]azirinederivatives could also be further transformed into intriguing
开发了 Rh(III) 催化的 α-酮肟的 C-H 活化和与重氮化合物的环化级联反应,以良好的产率构建高度稠合的茚满并[1,2- b ] 氮杂环丙烷骨架,并具有广泛的底物范围反应条件温和。更有趣的是,在该反应中首次证明了[4+1+1]顺序环化级联反应,并为α-酮肟开辟了新的反应模式。这些融合的茚满并[1,2- b ]氮丙啶衍生物也可以进一步转化为有趣的特权药物支架。
