Alkylation of phenol with natural α- and β-pinenes in the presence of Al(OPh)3 gives the O- and C-alkylation products with the structurally different terpene fragments. The terpenophenols obtained have proved to be optically active.
Alkylation of phenol by β-pinene in the presence of aluminum phenolate
Chukicheva,Shumova,Kuchin
experimental part, p. 43 - 46 (2012/07/17)
The alkylation of phenol by β-pinene using Al(OPh)3 as a catalyst was studied. It was found that the composition of the products depended on the ratio of starting materials. The principal products were chromane-type ethers with an equimolar ratio of starting materials and an excess of phenol. ortho-Alkylated phenol and an ether with a terpene substituent of bornyl structure were formed with a two-fold excess of β-pinene.
Separation of racemic ortho-isobornylphenol into enantiomers and evaluation of their antioxidant activity

experimental part, p. 614 - 618 (2012/02/15)
Racemic ortho-isobornylphenol was separated into enantiomers through diastereomeric camphanates. The absolute configuration of chiral centers of the isolated products was determined by X-ray studies. Antioxidant activity and membrane-protective properties
