A method for the highly regio- and enantioselective oxidative coupling of resorcinols has been established by using dibrominated dinuclear vanadium(V) catalyst 1c under air. When resorcinols bearing an aryl substituent were applied as substrates to the co

The ipso-substitution of one (or two) hydroxy groups of phloroglucinol with arene nucleophiles (e.g., o-xylene, tetralin, biphenyl) can be achieved easily under Friedel-Crafts-type conditions with or without the use of organic solvents affording a variety of 3,5-dihydroxybiphenyls (57-89% yields). The new method has significant practical advantages compared to classical biaryl-coupling routes. Georg Thieme Verlag Stuttgart, New York.

Suzuki and Stille cross-coupling reactions were utilized in the synthesis of 5-substituted 1,3-dimethoxybenzerie and 5-substituted resorcinol derivatives. The substituted resorcinol derivatives were obtained in only three steps from inexpensive reagents. 1,3-Dimethoxybenzoic acid and 1-chloro-3,5-dimethoxybenzene were transformed into 1-iodo-, 1-bromo-, 1-trimethyltin-3,5-dimethoxybenzene and 3,5-dimethoxyphenyl boronic acid. 5-Allyl-1,3-dimethoxybenzene and 3,5-dimethoxybiphenyl derivatives were obtained via cross coupling reactions under mild conditions. HI, BBr3 and AlI3 were used to demethylate these dimethoxybenzenes into their resorcinol derivatives.
