Reaction of 2-aminothiazoline (1) with a,b-unsaturated carbonyl compounds 2 under mild conditions (acetone, room temperature) gives two diastereomers 5-R-7-hydroxy-5H-tetrahydrothiazolo[2,3-a]pyrimidines 3. According to 1 H NMR, major isomers of 3 have axial OH-groups whereas minor isomers have equa
