Abstract: Ketones that are flanked by an allylic alcohol and an alkene isomerize to spirocyclic ethers in the presence of Re2O7 through allylic alcohol transposition, oxocarbenium ion formation, and Prins cyclization. These processes provide significant increases… read more here.

DOI: 10.1021/acsomega.7b01705
Abstract: Simple and readily available iron(III) triflate turned out to be a cheap, environmentally benign, and efficient catalyst for the direct etherification of alcohols. The use of ammonium chloride as an additive (5 mol %, 1… read more here.

DOI: 10.1021/jacs.2c02813
Abstract: Oxidative coupling and oxidative rearrangement are two of the most common biosynthetic strategies to form diaryl ethers. In contrast, enzymatic diaryl ether generation that proceeds in a nonoxidative manner has not been characterized thus far.… read more here.
