Low temperature addition of functionalized alkyllithium reagents to p-benzoquinones produces 4-alkyl-4-hydroxycyclohexa-2,5-dienones, and reaction of excess of the reagents with quinones yields 1,4-dialkylcyclohexa-2,5-diene-1,4-diols. With 4-acetoxy-, 4-hydroxy-, and 4-methoxy-4-methylcyclohexa-2,5-dienones the corresponding dienols are obtained. A one-step synthesis of the antibiotics 4-acetamido-
