Herein, we describe a mild and efficient Zn(II)-mediated electrophilic selenocyclization reaction of readily available and stable 3,4-O-isopropylidene-protected hydroxyalkenyl sulfides to 2-deoxy-2-phenylselenenyl-1-thio-glycosides This material was transformed into a 2-phenylselenenyl glycal in a controlled manner using an activation-elimination sequence (C) 2010 Elsevier Ltd.
