(Chemical Equation Presented) Investigation of cycloadditions of C-aryl-N-(4-chlorophenyl)nitrones to N-cinnamoyl piperidines was carried out. Two diastereoisomeric and one regioisomeric cycloadducts, and in some cases ring-opened compounds were characterized by spectroscopic and X-ray data. Molecular modelling was carried out for conformational studies.

Investigation of the cycloaddition of C,N-diarylnitrones to methyl cinnamate under different reaction conditions were carried out. Two diastereoisomeric and one regioisomeric cycloadducts were isolated and characterized by spectroscopic and X-ray data. Remarkable change in selectivity was noticed in solvent-free condition and in the presence of ytterbium triflate as catalyst. © 2011 Taylor & Francis Group, LLC.
