The imine of 2-aminomethylpyridine reacts similarly. Reversal of cycloaddition regiochemistry, together with complete asymmetric induction, occurs when titanium (IV) complexes are used as catalysts. The absolute configuration of one of the cycloadducts has been established by X-ray crystallography. © 1990.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyChemistryPharmacology, Toxicology and PharmaceuticsArticleSCOPUS10.1016/S0040-4039(00)97119-3
