Stereochemistry of the B/C ring junction in 3-benzylidenebenzo[a] quinolizidines

A trans B/C ring junction has been found to exist in 3‐benzylidinebenzo[a]quinolizidines. 1H NMR analysis of partially deuteriated compounds showed that the signals at 4.0‐4.2 ppm should be assigned to the H‐4‐exo proton.
