Abstract
A combination of homo‐ and heteronuclear 1D and 2D NMR techniques provided the assignment of the ^1^H and ^13^C resonances of the major component of a reaction product consisting of the two possible diastereomers of (5^′^S)‐1‐[2^′^‐(2‐hydroxyethyl)tetrahydropyran‐5^′^‐yl]‐1__H__‐pyrimidine‐2,4‐dione and showed that the tetrahydropyranyl ring in the major 5^′^S,2^′^S‐isomer adopts the twist conformation.
