Abstract
Squaric acid derivatives react with organolithium compounds at room te mperature to afford with excellent yields after hydrolysis, symmetrica l and unsymmetrically substituted oxygenated 1,4-diketones bearing alk yl, aryl or heteroaryl groups at the carbonyl positions. In the case o f aromatic or heteroaromatic ketones the enol tautomers are also obtai ned
