salt. All subsequent transformations proceed stereospecifically. The absolute configurations at the sulfur atoms of both sulfonimidamides were determined by comparison of measured and calculated CD spectra. An X‐ray crystal structure determination of a sulfonimidoylguanidine derivative confirmed this result.
