The reaction of phenol with 1-methylcycloalkenes in the presence of phosphorus-containing zeolite Y
摘要:
The results of cycloalkylation of phenol with 1-methylcyclopentene and 1-methylcyclohexene in the presence of phosphoric acid-impregnated zeolite are presented. Optimal conditions for the synthesis of 4(1-methylcycloalkyl)phenols were found. It was shown that the yield of the desired products under the optimal conditions is 86.4-89.6% of the theoretical value. The structure of 4(1-methylcycloalkyl)phenols was established by means of spectral and chemical analysis techniques.

A series of 2-(aminomethyl)phenols was synthesized and tested in rats and dogs for saluretic and diuretic activity. A number of these compounds exhibit a high order of activity on iv or po administration. The most active compounds belong to a subseries of 4-alkyl-6-halo derivatives of which 2, 2-(aminomethyl)-4-(1,1-dimethylethyl)-6-iodophenol, is the most active. Compound 2 also possesses significant

Dual Brønsted/Lewis acid catalysis involving environmentally benign, readily accessible protic acid and iron promotes site-selective tert-butylation of electron-rich arenes using di-tert-butylperoxide. This transformation inspired the development of a synergistic Brønsted/Lewis acidcatalyzed aromatic alkylation that fills a gap in the Friedel–Crafts reaction literature by employing unactivated tertiary
The ability of certain chemicals to mimic the effects of natural steroid hormones and their potential to disrupt the delicate balance of the endocrine system in animals has attracted much interest in recent years.Alkylphenolic chemicals have been reported to be weakly estrogenic. Estrogen receptor (ER) binding is primarily the result of interaction of the receptor with both a phenolic residue, and a hydrophobic pharmacophore. We have prepared and screened various phenols having a bulky 4-alkyl group, which may interact hydrophobically with the receptor, for estrogenic activity by using a previously described reporter gene assay employing COS-1 cells transfected with rat ERα-expression plasmid and an appropriate reporter plasmid. Some of the tested compounds, such as 4-(1-adamantyl)phenol and 4-cycloalkylphenols, exhibited much more potent activity than the typical estrogenic alkylphenol, 4-tert-octylphenol.
