Abstract

Er(OTf)₃ is a useful catalyst for the Ferrier rearrangement furnishing 2′,3′-dideoxy pyranosyl nucleosides easily by means of cleaner reaction profiles, short reaction times, mild reaction conditions, good stereoselectivity, and good recoverability of the commercially available catalyst.

Key words

Ferrier rearrangement - erbium(III) triflate - Lewis acid catalyst - nucleosides - glycals
