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。

functionalization of C(sp3)–H bonds with isoquinolines via a radicalprocess without ligands was achieved. The present system exhibits a novel pathway for the preparation of N-alkyl (benzyl) isoquinolin-1(2H)-ones in moderate to high yields. In addition, this procedure provides a simple method to afford 5-oxaprotoberberinones and their derivatives in two steps.

1-PHTHALAZINONE AND 1-PHTHALAZINONE DERIVATIVES OF THE FOLLOWING FORMULA: ##STR1## wherein R.sup.1 represents a hydrogen atom, an alkyl group, an aralkyl group, an acyloxyl group, an alkoxyl group, a halogen atom, a nitro group, an amino group or an amido group; and R.sup.2 represents a hydrogen atom, an alkyl group or an aryl group. Such can be prepared at good yields by the reaction of a benzoic acid derivative of the following formula: ##STR2## wherein R.sup.1 has the same meanings as defined above; X represents a halogen atom; and Y represents a hydroxyl group, an alkoxyl group or a halogen atom; with hydrazine or a hydrazine derivative of the following formula: R.sup.2 -- NH -- NH.sub.2 (III) wherein R.sup.2 has the same meanings as defined above.

Microwave irradiation of 1(2H)-phthalazinone with benzyl halides and potassium carbonate in dimethyl-formamide afforded 2-benzyl-1(2H)phthalazinones in modest yields. These products were tested in mice and rats in maximal electroshock and pentylenetetrazole seizure models for anticonvulsant activity, and in the rotorod test for neurotoxicity. A majority of the compounds exhibited anticonvulsant protection
