Peroxygenase from Agrocybe aegerita catalyses the selective hydroxylation of tertiary C–H bonds, whereby tertiary alcohols, diols, ketols, etc., were obtained in good to high regioselectivity and turnover numbers. This method can also be expanded for late-stage functionalization of drug molecules, which represents a streamlined synthetic method to give access to useful compounds.

The hybrid calix[2]phenol[2]pyrrole 4 and the fused pyrrolidine-containing macrocycle 9 were synthesized from two different isomeric starting materials, namely dimethyl 2-hydroxyisophthalate and 5-hydroxyisophthalate, respectively. The fused species 9 is devoid of obvious substrate binding properties. In contrast, the heterocalix system 4 displays the fluoride-induced conformational changes characteristic of the parent system.
