Nuclear megnetic resonance spectroscopy and the structures of the regioisomeric products of the cycloaddition of C-ethoxycarbonyl-N-arylnitrilimines to α,β-unsaturated ketones

(1)H NMR chemical shifts were used to assign the structures of the regioisomeric products obtained from the reactions of C-ethoxycarbonyl-N-arylnitrilimines 2A-E to α,β-unsaturated ketones 3a-j.The assignments were based on the large observed difference b
