Provided herein are naphthoquinones compounds such as those with a hydrogen bond donating group of the formula (I): wherein: R1, R2, R3, R4, R5, and n are as defined herein. Also provided herein are pharmaceutical composition of the present compounds and methods of treatment using the compounds including their use in the treatment of cancer.
An efficient Pd(II)-catalyzedoxidative annulation of 2-hydroxynaphthalene-1,4-diones and internal alkynes has been developed with high step efficiency. A broad range of functional groups are compatible with this reaction, thus providing a new entry to diverse naphtho[2,3-b]furan-4,9-dione derivatives in good to high yields.
Access to Aryl‐Naphthaquinone Atropisomers by Phosphine‐Catalyzed Atroposelective (4+2) Annulations of δ‐Acetoxy Allenoates with 2‐Hydroxyquinone Derivatives
of various chiral carbon centers, its synthetic potential toward an enantioenriched atropisomer has not been explored yet. Reported herein is a phosphine-catalyzed atroposelective (4+2) annulation of δ-acetoxy allenoates and 2-hydroxyquinone derivatives. The reaction provides expedient access to aryl-naphthaquinone atropisomers by the de novo construction of a benzene ring. The two functionalities of
Copper-Catalyzed Cascade 1,4-Addition/Annulation/Hydrolysis of Propargylamines with 2-Hydroxynaphthalene-1,4-diones: Direct Formation of 12-Phenacyl-11<i>H</i>-benzo[<i>b</i>]xanthenes
12-phenacyl-11H-benzo[b]xanthene-6,11(12H)-dione derivatives through copper-catalyzed cascade reaction of propargylamines with 2-hydroxynaphthalene-1,4-diones has been developed. The procedure is proposed to go through a sequence of 1,4-conjugate addition, intramolecular nucleophilic addition/dehydration, and hydrolysis of alkyne followed by an enol–ketone tautomerization. The reaction provides a new
通过铜催化炔丙基胺与2-羟基萘-1,4-二酮的级联反应构建12-苯甲酰基-11 H-苯并[ b ]并蒽-6,11(12 H)-二酮衍生物的新颖而通用的方法发达。建议该程序通过以下步骤进行:1,4-缀合物加成,分子内亲核加成/脱水和炔烃水解,随后是烯醇-酮互变异构。该反应为合成12-苯甲酰基-11 H-苯并[ b ] x吨-6,11(12 H)提供了一种新的高效方法。)二酮通过一步就可以从容易获得的起始原料中以高到高收率(70-88%)形成广泛的官能团相容性而形成三个新的键和一个杂环。
