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。
One-Pot Tandem Access to Phenothiazine Derivatives from Acetanilide and 2-Bromothiophenol via Rhodium-Catalyzed C–H Thiolation and Copper-Catalyzed C–N Amination

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
10H-Phenothiazine-3-carbaldehyde derivatives were obtained in moderate yields by the Duffformylationreaction, and 10-acetyl-phenothiazine derivatives were obtained in excellent yields by acetylating phenothiazine derivatives with acetic anhydride. A theoretical explanation for the chemoselectivity and regioselectivity of these acylationreactions applied to phenothiazine substrates was attempted by molecular-modeling
