Reaction optimization studies identified room temperature as well as microwave-mediated procedures, providing moderate to good yields (57-88\%) in the thiophenol-mediated epoxide opening and intramolecular aldol reaction. In addition, the isolation of a key intermediate and in situ NMR studies supported the mechanistic hypothesis. The bicyclic ring products occupy novel chemical space according to ChemGPS and Chemaxon chemical diversity and cheminformatics analyses. {\copyright} 2010 Elsevier Ltd.} }
