“…The spectra of X-XVI contained two new signals, an unresolved four-proton multiplet at δ 2.21-2.28 ppm (CH 2 CH 2 ) and a diffuse signal at δ 7.60-7.70 ppm (exchangeable protons of the carboxy Amine VII [14] was synthesized according to modified procedure [15] from the cyclopentadiene adduct with acrolein. The spectra of X-XVI contained two new signals, an unresolved four-proton multiplet at δ 2.21-2.28 ppm (CH 2 CH 2 ) and a diffuse signal at δ 7.60-7.70 ppm (exchangeable protons of the carboxy Amine VII [14] was synthesized according to modified procedure [15] from the cyclopentadiene adduct with acrolein.…”
