[GRAPHICS]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.
Synthesis of a Nitrogen Analogue of Sphingomyelin as a Sphingomyelinase Inhibitor
GraphicsSphingomyelin nitrogen analogue 1 was designed and synthesized as a sphingomyelinase inhibitor. The synthesis was established by continuous Hofmann rearrangement and Crutius rearrangement as key steps in constructing the 3-hydroxy-1,2-diamine structure in the backbone of 1. This analogue showed moderate inhibitory activity toward SMase isolated from B. cereus.
