Herein, we report a base-free malononitrile activated condensation of 3-methylquinoxaline-2(1H)-one (3MQ) 1 with aryl aldehydes 3a-3ad for synthesis of styrylquinoxalin-2(1H)-ones (SQs) 4a-4ad with excellent yields. In this reaction, malononitrile activates the aldehyde via Knoevenagel condensation towards reaction with 3MQ 1 and gets liberated during the course of reaction to yield the desired SQs 4a-4ad. The SQs were evaluated for in vitro cholinesterase inhibition and 4n was found to display a mixed type of inhibition of AChE, which was supported by molecular modelling studies. This study has led to the discovery of a new chemotype for cholinesterase inhibition which might be useful in finding a remedy for Alzheimer's disease.

In this study, certain 3-substituted styrylquinoxalin-2(1H)-ones (2a-d) and their 2-chloro (3a-d) and 2-piperazinyl derivatives (4a-g) were synthesized from 3-methylquinoxalin-2(1H)-one (1). In addition, a series of 1-alkyl-3-substituted styrylquinoxalin-
