✦ Synopsis

In the n.m.r. spectrum of the sulphenamide cl),1 two doublets are observed for group at 6 0.93 and 1.48 (CFC13). Repeated crystallisation from light petroleum gave the methyl one diastereoisomer containing only the doublet at 6 0.93; the other diastereoisomer containing only the doublet at 6 1.48,was obtained by chromatography over Kieselgel.
