presence of Lewis acids to afford homochiral 2(5H)-furanone derivatives. The structures of these products have been determined using nmr spectroscopy and, where possible, by X-ray analysis. Preliminary experiments have been carried out involving conjugate addition to these unsaturated lactones, demonstrating their potential as substrates for natural product synthesis.
