Reduction of acetals with samarium diiodide in acetonitrile in the presence of Lewis acids

Modulating chitin synthesis in marine algae with iminosugars obtained by SmI2 and FeCl3-mediated diastereoselective carbonyl ene reaction

Strategies for synthesizing polyhydroxylated piperidines such as iminosugars have received broad attention. These substances are known to interact with carbohydrate related enzymes glycosidases and glycosyltransferases, to which also the large...

A multicomponent approach to the synthesis of 1,3-dicarbonylic compounds

A general synthesis of 1,3-dicarbonylic compounds using multicomponent reactions of isocyanides is described. The process involves a Passerini three-component condensation of glyoxal derivatives, isocyanides and acetic acid, followed by metal mediated reductive or solvolytic removal of the acid component. Noteworthy, reductive deacetoxylation of Passerini glyoxylamide adducts was successfully achieved using photochemically activated SmI(2). This procedure constitutes a novel convenient method for the direct synthesis of malonic retro-peptidic subunits.
