Abstract

A facile deoxygenation of a systematic series of substituted 2,2-dimethyl-7-hydroxy-4-chromanones via their sulfonate, isourea, and thiocarbamate derivatives is reported. The synthesis of novel 2,2-dimethyl-7-mercapto-4-chromanones has been accomplished by the hydrolysis of the corresponding thiocarbamates. The scope and limitations of different deoxygenation procedures in the case of these hydroxybenzopyranoids are also presented.
