Abstract

An unnatural tricyclic oxaterpenoid, obtained by treatment of the sesquiterpene synthase presilphiperfolan-8β-ol synthase (BcBOT2) with an unnatural farnesyl pyrophosphate ether derivative, itself obtained by chemical synthesis, was converted in oxidation studies as part of a broad screening program by selected unspecific peroxygenases (UPOs). Product analysis revealed that Agrocybe aegerita UPO, its mutant PaDa-I, and two commercial ones, UPO₅₄ and UPO_49, provided new oxidation products with sufficient efficiency for subsequent upscaling that allowed product isolation and structure elucidation. As such new terpene-based oxiranes and hemiacetals were formed by UPO-mediated epoxidations and CH-activation. The structure elucidation was further supported by comparison with products generated by chemical oxidation.
