An in-depth study of the oxirane ring-opening reaction of a pivotal epoxypyrrolidine is reported. The introduction of various carbon- and heteroatom-centered nucleophiles at C4 has been achieved with high regiocontrol. The structures of the major products were assigned on the basis on an X-ray crystallographic study of six examples. A mechanistic study carried out at the B3LYP/6-31G** level of theory suggested that the steric control of the vinyl substituent was responsible for the regioselectivity. Finally, this approach was used to design and prepare imino-sugar-based sphingolipid mimics. A highly cytotoxic C-octylpyrrolidine is described. This compound was shown to interfere with the metabolism of sphing-olipids in murine melanoma cells, notably in inhibiting the production of glucosylceramide. Wiley-VCH Verlag GmbH & Co. KGaA.

The stereoselective preparation of C-alkyl 5-membered ring imino sugars, their biological evaluation with regard to glucosyleramide synthase (GCS) inhibition, and cytotoxicity in a murine melanoma B16 cell model, were investigated. It was found that epoxy
