2,2′-Anhydrouridine has been successfully converted into the appropriate 2′-amino-2′-deoxyuridine derivatives in a reaction with isothiocyanates obtained from amino acids or α,ω-diaminoalkanes. The initially formed oxazolidine-2-thione ring is cleaved under basic conditions into the corresponding 2′-amino(substituted)-2′-deoxyuridine derivatives. The implemented additional terminal functionality in the substituent attached to the 2′-amino group allows further modifications with e.g., fluorophore moiety.

Investigation of the reaction of thiophosgene with Δ2-oxazolines I, Δ3-thiazolines II, 4H-benzothiazines III, 2-methoxypentahydro-Δ1-azepine IV, theophylline and caffeine showed that only compounds I and IV reacted to give 2-acyloxyethyl isothiocyanates and methyl 6-isothiocyanatohexanoate.The structure of these products was corroborated by IR, 1H NMR, 13C NMR and mass spectral methods.The suitability of the above-mentioned compounds to react is discussed.
