Abstract
The combination of the oxidative intramolecular [4+2]cycloaddition of o-acylphenol derivatives 10a,b and 16 having the ω-phenylthioethynyl group in the acyl chain and the Pummerer-type reaction of the cyclization products afforded the peri-hydroxy dihydroquinones 9a,b and 18 in good overall yields.Keywords
