Isoquinoline compounds for treating various diseases and pathologies are disclosed. More particularly, the present disclosure concerns the use of an isoquinoline compound or analogs thereof, in the treatment of disorders characterized by the activation of Wnt pathway signaling (e.g., cancer, abnormal cellular proliferation, angiogenesis, Alzheimer's disease, lung disease, inflammation, auto-immune diseases and osteoarthritis), the modulation of cellular events mediated by Wnt pathway signaling, as well as neurological conditions/disorders/diseases linked to overexpression of DYRK1A.

conversion of lignin into heteroatom functionalized chemicals is of great importance to bring the biorefinery concept into reality. Herein, a new strategy was designed for direct transformation of lignin β-O-4 model compounds into benzylamines and phenols in moderate to excellent yields in the presence of organic amines. The transformation involves dehydrogenation of Cα−OH, hydrogenolysis of the Cβ−O
Divergent reaction: metal & oxidant free direct C–H aryloxylation and hydride free formal reductive N-benzylation of N-heterocycles

Metal, oxidant and other additive-free novel methods for direct C–H aryloxylation of aliphatic amines are developed. In the presence of excess amine, the course of the reaction was diverted, producing various arylmethylamines via hydride-free formal reductive amination. Involvement of a quinonemethideintermediate was revealed from mechanistic studies.

The mechanism of the ring closure of [2-(1-pyrrolidinyl)phenylmethylene]-propanedinitrile (2a) to l,2,3,3a,4,5-hexahydropyrrolo[1,2-a]quinoline-4,4-dicarbonitrile (3a) has been studied by kinetic measurements using 1H-NMR spectroscopy. It could be shown that the rate-determining step consists of an intramolecular 1,5 hydrogen transfer, which is accompanied by charge separation within the- molecule
[2-(1-吡咯烷基)苯基亚甲基]-丙腈(2a)对1,2,3,3a,4,5-六氢吡咯并[1,2 - a ]喹啉-4,4-二腈的闭环机理(3a)已经通过使用1 H-NMR光谱的动力学测量来研究。可以表明,确定速率的步骤由分子内1,5氢转移组成,该转移伴随着分子内的电荷分离。计算出的2a(AM1)和实验(X射线)分子结构非常吻合。在基态几何结构中,最有可能发生1.5的氢转移。随后,前一个乙烯基的旋转和CC键的形成(导致六元环)也以立体化学定义的方式发生。
