Regioselectivity in the Reactions of Methoxydehydrobenzenes with Furans. Part 2. 2-Methoxyfuran and Methoxydehydrobenzenes
Giles, Robin G. F.,Hughes, Andrew B.,Sargent, Melvyn V.
, p. 1581 - 1587 (2007/10/02)
Acid-induced ring opening of adducts of furan and methoxydehydrobenzenes gives the naphthalenols derived from the more stable carbocation.The cycloadditions of methoxydehydrobenzenes containing a 3-methoxy group and 2-methoxyfuran are highly regiospecific
Methylation of 3,3'-Dihydroxylated 2,2'-Binaphtho-1,4;1',4'-quinones
Laatsch, Hartmut
, p. 393 - 400 (2007/10/02)
Monomeric hydroxy-p-quinones (1) are in equilibrium with the corresponding o-quinones (2) and on methylation, a mixture of both isomeric ethers is obtained.In contrast, dimeric hydroxynaphthoquinones with 3a-skeleton in treatment with diazomethane are yie
A New Synthesis of ortho-Quinones by Transition-Metal-Mediated Oxygenation of Phenols with tert-Butylhydroperoxide and the Mimoun Oxodiperoxo Molybdenum Complex * Py * HMPT
Krohn, Karsten,Rieger, Hagen,Khanbabaee, Karamali
, p. 2323 - 2330 (2007/10/02)
A specific oxygenation of phenols to ortho-quinones can be effected by a combination of the transition metal complexes Ti(OiPr)4, VO(acac)2, Zr(acac)4, Zr(OnPr)4 and tert-butylhydroperoxide (TBHP) or * Py * HMPT.Naphthols, anthracenols, phenanthrols and donor substituted mononuclear phenols are readily converted into the corresponding 1,2-quinones.Unhindered ortho-naphthoquinones can yield binaphthyls with unreacted starting material by Michael addition. - Key Words: ortho-Quinones / tert-Butyl hydroperoxide / Phenols, oxygenation
