The reaction of 4 with CbzNSO was attempted in different solvents to determine the stereoselectivity and acetonitrile was found to be the best in terms of yield and diastereoselectivity. {A table is presented}

The inversion of sulfur configuration is based on our earlier work using N-Ts sulfilimine as the intramolecular nucleophile, see Ref. 6. The syn disposition of the substituents at C2 and C3 in 7a was proven by NOE studies on the acetonide derived from 15.

The result obtained herein is in contrast to that reported by Garcia-Ruano and co-workers (Ref. 5a) who report recovery of the starting material from a syn-amino alcohol derivative.
