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.

The purity of recovered Er(OTf)3 was confirmed by comparison with the IR spectrum of the commercial product.
