this is a cosy HQMC of N-benzyl-2-azanorbornene , please assign each peak and account for the observed coupling constant!

additional info 13C NMR of the same compound is also provided

thank you so much

Answer 1

With the help of the provided spectral data as the cosy HQMC and ¹³C NMR of N-benzyl-2-azanorbornene, we have tried to assign the peaks in ¹H NMR and ¹³C NMR as below,

The A 2314 endo N-benaul-2020- narbornene 8 91 12 Total 13 combons present LANMR ppm) :- 7.5-7.3 -(m, 5H, ArH, 10,11,12,10 11') 6.5 (dd in olefinic 5) 6:2 (old, it definit, 6) 2.9 (S, N-12,8), 3.6 (d, 11, 9). 3.3(m, 14 4 ) , 2.2(d, 1H=eX037 = 3 H2) 2.460, 197= endo), 0.9-0.8(m, 24, 7) 139.5 (9 €) 13 6 4 (5, CH=oletnic), 130.866, CH - olefinic), 128.7-128.0/10, 10 11 11- 4.
