“…The obtained results were explained by the fact that the base 11 reacts with its predominantly trans-fused form 11A [17,26], which has three anticoplanar fragments: H C and the unshared electron pair of the nitrogen atom.…”

The cis-trans conversion in pyrrolizidines and the deciding effect of steric factors on their conformational equilibrium are discussed. Work on the synthesis and characteristics of sterically strained pyrrolizidines is analyzed and discussed. It is shown that such compounds (predominantly trans-fused) have a series of features in their properties that greatly distinguish them from unstrained pyrrolizidines. The first results from study of the thermodynamics of cis-trans conversion of the pyrrolizidine bicycle are summarized.
