Structural characterization of (±)-N-chloro-2,2-bis(methoxycarbonyl)aziridine by X-ray crystallography and 2D NMR spectroscopy
Abstract
The X-ray crystal structure analysis for racemic N-chloro-2,2-bis(methoxycarbonyl)aziridine is reported. The complete assignments of the 1H, 13C and 17O chemical shifts are performed using 2D NMR techniques (C–H COSY, COLOC) to establish unequivocally the relative configuration of the aziridine.
