A large group of derivatives of 3-furoic acid and 3-furyl ketones can be prepared in high yield by a process which consists of reacting an .alpha.,.beta.-unsaturated ketone having either an .alpha.-carboalkoxy or .alpha.-acyl group with N-bromosuccinimide and thermally cyclizing the resulting bromine containing intermediate.
