A number of beta-aminocinnamonitriles have been prepared by the reaction of salts of acetonitrile and propionitrile with benzonitrile. These materials were evaluated in the carrageenan antiinflammatory screen in Royal Hart, Wistar strain rats. Despite good weight gains in the parent molecule, beta-aminocinnamonitrile (1), only marginal activity was found in related compounds and some possible "metabolites
Annulation of β-Enaminonitriles with Alkynes via Rh<sup>III</sup>-Catalyzed C–H Activation: Direct Access to Highly Substituted 1-Naphthylamines and Naphtho[1,8-<i>bc</i>]pyridines

A Cp*RhIII-catalyzed oxidative annulation of β-enaminonitriles with alkynes was reported to achieve selective synthesis of polysubstituted 1-naphthylamines and naphtho[1,8-bc]pyridines via multiple C–Hactivations. Assisted by a naphthylamine NH2 group, 1-naphthylamines were also readily cyclized to produce naphtho[1,8-bc]pyridines. In addition, the obtained naphtho[1,8-bc]pyridine derivatives exhibit
据报道,Cp * Rh III催化的炔烃对β-烯腈的氧化环化反应通过多种C-H活化选择性地合成了多取代的1-萘胺和萘[1,8- bc ]吡啶。在萘胺NH 2基团的辅助下,1-萘胺也很容易被环化以生成萘[1,8- bc ]吡啶。此外,所获得的萘并[1,8- bc ]吡啶衍生物在固态下表现出强烈的荧光。
Highly Efficient Rh<sup>I</sup>-Catalyzed Asymmetric Hydrogenation of β-Amino Acrylonitriles
It takes two to TangPhos: β‐Amino acrylonitriles can be readily prepared from acetonitriles. Both of the E/Z isomers undergo hydrogenation with excellent enantioselectivity by using the Rh–TangPhos (TangPhos=1,1′‐di‐tert‐butyl‐(2,2′)‐diphospholane) catalyst system. The products, chiral β‐amino nitriles, are valuable chiral building blocks for many drugs.
