    • 1H NMR signal of the proton next to the ester function with those of the related compounds described by Doyle et al.: Doyle, M. P.; Dorow, R. L.; Tamblyn, W. H. J. Org. Chem. 1982, 47, 4059-4068. This particular proton is reported at 1.86 ppm for the cis isomer and at 2.31 ppm for the trans isomer. Ours resonates at 2.30 ppm, thus indicating a trans relationship between the ester and the cyano moeties.
