Hydroxyalkylation of α-C−H Bonds of Tetrahydrofuran with Aldehydes in the Presence of Triethylborane and tert-Butyl Hydroperoxide

Abstract
The alpha-hydroxyalkylation of tetrahydrofuran with aldehydes via radical C-H abstraction was conducted using triethylborane in the presence of tert-butyl hydroperoxide. This study presents a rare instance of direct intermolecular radical addition of unactivated cyclic ether to aldehydes.
