Abstract
The reaction of 3,4-diamino-2,2,6,6-tetramethylpiperidine-1-oxyl with (1S)-(+)-camphor-10-sulfonyl chloride gives a mixture of diastereomeri c 4-monosulfonylamino derivatives. The products of their acylation hav e been obtained. The 3,4-bis-[(1S)-camphor-10-sulfonylamino] derivativ e was synthesized and resolved to individual diastereomers. For one of them the trans relationship of the 3- and 4-substituents and the abso lute (3S,4R)-configuration were established by X-ray structural analys is.
