Abstract: A potential chiral auxilliary, (+)-camphor derived N-propionyl sultam, wassynthesized from (+ )-camphor-10-sulphonyl chloride in four steps with enan-tiomerical purity.The molecular and crystal structures of the title compound weredetermined by single crystal diffraction analysis.The crystal belongts to monoclin-ic, space group P21 with cell dimentions a= 1.0502(4), b= 0.7252(1 ), c= 0.9363(2) nm, β= 108.3(5), V = 0.677 nm3, F(000) = 292 and Z= 2.The structuralcharacteristics with respect to the potential utility for the stereoselective alkylationat a-carbon of the N-propionyl group are discussed and explained based on 1H-, 13C-NMR.MS and X-ray analysis.
