Oxidation of castanospermine (1) (HlO4) and its 6-O-acetyl derivative 7 [Pb(OAc)4], followed by reduction and acetylation, were reported. A mechanism is proposed for the novel Pb(OAc)4 oxidation of a beta-tertiary amino alcohol.

Red blood cells which are infected with the parasite P. falciparum cause the cells to become sticky and less deformable. This results in a build-up of cells on the vascular wall and creates occlusions to blood flow which are thought to cause the cerebral, renal and liver complications of P. falciparum infections. Certain esters of castanospermine prevent or reduce the adhesion of falciparum infected blood cells to the vascular endothelial wall and are a useful adjunct in the treatment of malaria.
Certain Castanospermine ester derivatives are disclosed to be effective in treating retroviral infections including HIV infections and are thus useful in the treatment of AIDS and ARC.
