## Abstract The ^1^H NMR spectra of E/Z 2βhydroxyindolenines are reported in both CDCl~3~ and DMSOβd~6~ solvents. The data suggest a preferred conformation of the heterocyclic ring, which is slightly distorted from planarity, in agreement with the xβray crystallographic data of one of the isomers.
## Abstract ^13^C and ^15^N NMR data for twelve __N__βunsubstituted pyrrolidines are reported and __cis__ and __trans__ stereomers are assigned for 2,3β, 2,4β and 2,5βdisubstituted compounds.
