Abstract
An area of great interest in recent years has been chalcones. Chalcones are the important component of many natural sources and have variety of biological activities. Chalcones which are also known as α,βunsaturated ketones is an significant class of organic compounds and reported to possess a wide spectrum of biological activities such as antibacterial, antifungal, anticancer, anti-inflammatory etc. Abundant research papers have been published and chalcones continue to show promise for new drug investigations. The derivative of chalcones were prepared using Claisen–Schmidt condensation scheme. The structure of the synthesized was confirmed by UV and IR. The compound was also tested for their antimicrobial activity
