Access to Orthogonal Protected Phenols – Synthesis of a Silylated Quinol
In the course of studies towards the total synthesis of Elisabethin A (1), it was necessary to elaborate a synthetic strategy for a quinol which is protected orthogonally to a methylether. Elisabethin A is a natural product which was isolated from the Caribbean gorgonian Pseudopterogorgia elisabethae (Octocorallia) [1]. Marine natural products are among the most promising sources of new biologi...
متن کاملTime-resolved photoelectron imaging of excited state relaxation dynamics in phenol, catechol, resorcinol, and hydroquinone.
Time-resolved photoelectron imaging was used to investigate the dynamical evolution of the initially prepared S(1) (ππ*) excited state of phenol (hydroxybenzene), catechol (1,2-dihydroxybenzene), resorcinol (1,3-dihydroxybenzene), and hydroquinone (1,4-dihydroxybenzene) following excitation at 267 nm. Our analysis was supported by ab initio calculations at the coupled-cluster and CASSCF levels ...
متن کاملDetermination of catechol and quinol in the urine of workers exposed to benzene.
Time weighted average concentrations of benzene in breathing zone air (measured by diffusive sampling coupled with FID gas chromatography) and concentrations of catechol and quinol in the urine (collected at about 1500 in the second half of a working week and analysed by high performance liquid chromatography) were compared in 152 workers who were exposed to benzene (64 men, 88 women). The conc...
متن کاملQuinol and Hydroxyquinol from the Ethereal Sulphate Fraction of the Urine of Rabbits Receiving Benzene Orally
[n the preceding paper it was shown that the average sum of the glucuronic acid and ethereal sulphate conjugations ofrabbits receiving benzene orally was about 20 %, and it was assumed that the conjugates excreted were those of phenolic substances. Of these phenols about one half was shown quantitatively to be phenol whereas the other half was probably a mixture of other phenols such as catecho...
متن کاملNew families of enantiopure cyclohexenone cis-diol, o-quinol dimer and hydrate metabolites from dioxygenase-catalysed dihydroxylation of phenols.
Toluene dioxygenase-catalysed cis-dihydroxylation of phenols has led to the discovery of new enantiopure cyclohexenone cis-diol, o-quinol dimer and phenol hydrate metabolites having synthetic potential.
