α-Alkoxystannanes undergo oxidation upon treatment with cerium ammonium nitrate generating oxonium ions, which can be trapped in an intramolecular fashion affording furo[2,3-b]pyrans.

The diastereoselective synthesis of 'pro-activated' analogues of cyclophosphamide in the 3-[bis(2-chloroethyl)amino]-2-aza-4,9-dioxa-3- phosphabicyclo(4.3.0)nonane 3-oxide series is described, using either the phosphorylation of an azidoalcohol followed by a reductive cyclisation or the phosphorylation of an acetal alcohol followed by an unprecedent direct Lewis acid catalyzed intramolecular substitution.
