Synthesis, chiral HPLC resolution and configuration assignment of 1-phenylglyceryl trinitrate stereomers

Abstract

As an introductory study of in vitro vasodilating activity, the access to the four stereomers of 1-phenylglyceryl trinitrate is described using achiral and chiral chromatography. For semi-preparative separation of the enantiomers, a Chiralcel OD (250 x 10 mm, 10 microm) was used. Catalytic reduction leading to the corresponding stereomers of 1-phenylglycerol allowed absolute configuration assignments. The same methods were used for the separation and configuration assignment of the enantiomers of 3-phenylpropane-1,2-diyl dinitrate.
