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.
