Prenylphenols and 2,2-dimethylbenzopyrans were synthesized via alkylation of resorcinol and pyrocatechol with prenol in the presence of aluminumisopropylate and phenolate catalysts. Several process features were determined. The antiradical, membrane-protective, and antioxidant activity of the synthesized compounds were assessed using various models. 2,2-Dimethyl-7-isobornylchroman-6-ol was found to

We herein report a serendipitously observed acid mediated rearrangement of monoethylene ketal of 2-methyl-2-(3-methylbut-2-en-1-yl)cyclohex-4-ene-1,3-diones to Dihydrobenzopyran and demonstrated the application of this methodology in the construction of core carbon scaffolds of dimethoxyajacareubin, cariphenone-A and crotamadine.
