The intramolecular cycloaddition to vinyl sulphur derivatives of a series of nitrones featuring an alkyl or alkoxy substituted α-stereocenter on the tether connecting dipol and dipolarophile occurs in a competely stereoselective fashion to give 3',3-anti configurated products.The synthetic potentialities of this reaction is illustrated by the synthesis of a precursor of (d)-biotin.
