酰胺选择性催化C–N键裂解为增值胺产品是一种理想的但具有挑战性的转化。含有亚氨基二苄基基序的分子普遍存在于药物分子和功能材料中。在这里,我们建立了一种组合的KOH / BEt 3催化剂,用于将酰基-亚氨基二苄基衍生物(包括非杂环羧酰胺)进行脱氨基硼氢化成相应的胺。这种新颖的无过渡金属的方法也被用于氯米帕明和发光体的构建。
A nickel-catalyzedKumadacoupling of aniline derivatives was developed by selective cleavage of aryl C–N bonds under mild reaction conditions. Without preinstallation of an ortho directing group on anilines, the cross-coupling reactions of Boc-protected aromatic amines with aryl Grignard reagents afforded unsymmetric biaryls. Mechanistic studies by DFT calculations revealed that the nickel-mediated

tertiary amides, including the biologically active aryl-phenazine carboxamides and the challenging non-heterocyclic carbonyl functions, using low-cost hydrosilane as a reducing reagent has been developed. The novel catalyst system exhibits high efficiency and exclusive selectivity, providing the desired amines in useful to excellent yields under mild conditions. Overall, this transitionmetal-free process
Disclosed are certain complexes of AFC compounds and binding agents. Such complexes are useful, among other things, in the treatment of inflammatory diseases or disorders.
