✦ Synopsis

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 the amide conjugation diminishes when nitrogen is incorporated into a three-membered ring.
