TiCl+-catalyzed Diels-Alder additions of the acrylate of commercial D-pantolactone to cyclopentadiene, isoprene and butadiene proceed with very high diastereofacial selectivity. Practical and mechanistic aspects of these reactions are discussed. Metal coordination is known to be important for a vari
