The present invention provides boron-containing isoquinoline compounds as protein kinase-modulating compounds. These compounds are useful as neuroprotective and neuro-regenerative agents for the amelioration of glaucoma and other ocular neuropathies.
An efficient asymmetric acyl-Mannichreaction of isoquinolines with α-(diazomethyl)phosphonate and diazoacetate has been developed using chiral spiro phosphoric acids as catalysts. This reaction allowed the construction of a series of chiral 1,2-dihydroisoquinolines bearing a tertiary stereocenter at the C1 position with up to 98% yield and 99% ee.
Iodine-Catalyzed Oxidative Functionalization of Azaarenes with Benzylic C(sp<sup>3</sup>)–H Bonds via N-Alkylation/Amidation Cascade: Two-Step Synthesis of Isoindolo[2,1-<i>b</i>]isoquinolin-7(5<i>H</i>)-one

An efficient and practical iodine-catalyzed oxidative functionalization of azaarenes with benzylicC–Hbonds via an N-alkylation and amidation cascade is developed to provide isoquinolin-1(2H)-ones. This method utilizes readily available unfunctionalized azaarenes and methylarenes as starting materials and proceeds under metal-free conditions with good to excellent yields, avoiding the use of expensive
通过N-烷基化和酰胺化级联反应,开发了一种有效且实用的碘催化的氮杂芳烃与苄基CH键的氧化功能化反应,以提供异喹啉-1(2 H)-one。该方法利用容易获得的未官能化的氮杂芳烃和甲基芳烃作为起始原料,并在无金属条件下以良好或优异的收率进行,避免了使用昂贵的贵金属催化剂以及避免产生卤化物和金属废物。该反应的合成效用以异吲哚并[2,1 - b ]异喹啉-7(5 H)-one的简明两步合成为例。

An oxidative multi-functionalization of azaarenes with benzylicC-Hbonds of methylarenes via iodination/N-benzylation/amidation cascade, to produce N-benzyl-4-iodoisoquinolin-1(2H)-ones and N-benzyl-3-iodoquinolin-2(1H)-ones is developed. The molecular iodine plays a triple role in activating benzylic sp3 C-H bond of methylbenzenes, accelerating the oxidation process and serving as iodination reagent

functionalization of isoquinolines with methylarenes is developed, which can be triggered by the selected oxidants to produce C 1 - or N -benzyl-substituted products selectively. This method utilizes readily available isoquinolines and methylarenes as starting materials and proceeds under metal-free conditions with broad substrate scope with respect to methylarenes, avoiding the usage of expensive metal
