Stereocontrolled synthesis of a sphingomyelin methylene analogue as a sphingomyelinase inhibitor.

ABSTRACT

[reaction see text]Efficient synthesis of a sphingomyelin methylene analogue, which was designed as a sphingomyelinase inhibitor, was stereoselectively achieved. The Hofmann rearrangement of the alpha-hydroxyethyl-beta-hydroxy amide 4 followed by the intramolecular oxazolidinone ring formation was one of the key steps.
