X-Ray crystallographic structure determination of an aziridinone. Demonstration of a non-planar arrangement at nitrogen in an α-lactam
Abstract
The X-ray crystal-structure analysis of 1,3-diadamantylaziridinone (1b) demonstrates that the configuration at nitrogen is pyramidal (N lying 0·534 Å from the plane defined by its three substituents) and that the adamantyl groups are trans to each other.
