Abstract

Pyrrolidine- and piperidine-fused 1,3,4,2-oxadiazaphosphinane 2-oxides were prepared by cyclization of the corresponding pyrrolidine- and piperidine-hydrazino alcohols by using phosphorus-containing reagents. Stereochemical and conformational analyses were carried out in order to determine the effect of the ring size on the conformational behavior of the nitrogen-bridged bicyclic system. It was found that the chair conformation in the pyrrolidine-fused 1,3,4,2-oxadiazaphosphinane 2-oxides can be shifted toward twisted or distorted conformations.
