โฆ Synopsis
The pyramidalization of the nitrogen in sulfonamides of 7-azabicyclo[2.2.1 ]heptane is enhanced in the solid state as compared with the corresponding monocyclic sulfonamides of pyrrolidine and 3-pyrroline. We postulate a general structural motif of pyramidal nitrogen in sulfonamides.

This work provides a proof of pyramidal configuration of nitrogen in N-acyldiaziridines I-IX and N-acyloxaziridine X (see Table 1)(2). In respect to the NMR time scale the inversion of this configuration is fairly slow. The data presented here are in agreement with an earlier observation (3) that th
