The 1H and 13C NMR spectra of methyl (E)-2,3-diphenylprop-2-enoate and methyl (E)-2-(2-phenylethenyl)benzoate resulting from the electrocyclic ring opening of benzocyclobutenone starting materials have been assigned.A combination of direct detection 2D NMR techniques, COSY, HETCOR, and FLOCK, provided the assignments of the 1H and 13C resonances. - Keywords: NMR 1H NMR 13C NMR Benzylidene derivatives

A series of α,β-epoxy-γ-butyrolactones were synthesized in moderate yields via oxiranyl remote anions derived from epoxy cinnamate esters. The key synthetic step involved deprotonation of the β-position of α,β-epoxy cinnamate derivatives where the generated β-anion was stabilized by remote chelation from an ester group. The substitution reaction of the anion with a variety of ketones, followed by cyclization, readily furnished the desired substituted α,β-epoxy-γ-butyrolactones.
