title: Stereocontrolled synthesis of LNA dinucleoside phosphorothioate by the oxathiaphospholane approach.
abstract: The application of the oxathiaphospholane approach for the stereocontrolled synthesis of LNA dinucleoside phosphorothioate is described. The reaction of ring opening condensation proceeds in CH3CN solution in high yield and with over 96% stereoselectivity. One of diastereomers of LNA dinucleoside phosphorothioate (presumably R(P)) was found to be readily digested by svPDE.
