Imidazo-oxazaphosphorines as Precursors to Chiral Phosphite Triesters
摘要:
New bicyclic imidazo-oxazaphosphorines underwent a highly diastereoselective displacement of the imidazole moiety upon reaction with various alcohols, leading to chiral phosphite triesters as single diastereomers. The introduction of a nucleoside on this bicyclic structure was investigated by several routes, leading to new nucleoside building blocks.

The diastereoselective synthesis of phosphite triesters and their corresponding thiophosphate triesters is described. The newbicyclic imidazo-oxazaphosphorine, synthesized as a single diastereomer, is used as an intermediate that undergoes a diastereoselective displacement when reacted with an alcohol. This process eliminates the use of an acid catalyst.
