A Green Approach for the One-Pot, Three-Component Synthesis of 2-Arylpyrroloacridin-1(2H)-Ones using Lactic Acid as a Bio-based Catalyst under Solvent-Free Conditions

A facile and benign synthetic strategy is proposed for the synthesis of 2-arylpyrroloacridin-1(2H)-ones via a lactic acid-catalyzed three-component reaction of dimedone, various anilines, and isatins under solvent-free conditions. Avoidance of hazardous o

An efficient synthesis of pyrroline-fused acridine derivatives catalyzed by silica sulfuric acid

A simple and efficient synthesis of pyrrolo[2,3,4-kl]acridine-1-one derivatives via the cascade reaction of isatins with enaminones catalyzed by silica sulfuric acid (SSA) has been established. In this reactions, SSA shows a highly catalytic nature: easy to handle procedure, short reaction time, recycle exploitation, insensitivity to air and moisture, and excellent isolated yields. The catalyst could be recycled at least five times.

An efficient synthesis of pyrrolo[2,3,4-kl]acridin-1-one derivatives catalyzed by L-proline

An efficient domino approach for the synthesis of novel pyrrolo[2,3,4-kl]acridin-1-one derivatives has been established. This reaction represents the first facile conversion of an isatin to a pyrrolo[2,3,4-kl] acridin-1-one via a C-N bond cleavage reaction without the need for a multistep reaction process.

An unexpected multicomponent reaction leading to 2-arylpyrrolo[2,3,4-kl] acridin-1(2H)-ones

An unexpected condensation profile was observed for the three-component reaction of 5,5-dimethyl-1,3-cyclohexadione (dimedone), various anilines, and isatin leading to the synthesis of novel 2-arylpyrrolo[2,3,4-kl]acridin-1(2H)- ones in the ionic liquid [
