## Abstract The synthesis of the first examples of Class II mesoionic thiazolopyrimidine acyclonucleosides (MTA) incorporating the 2,3‐dihydroxypropyl moiety as the sugar simulator is described. First, 2‐bromothiazole was reacted with excess 1‐amino‐2,3‐propanediol acetonide __via__ an aromatic nuc
## Abstract The 70 eV electron impact mass spectra of some 1,3,4‐thiadiazolo[3,2‐__a__]pyrimidin‐7‐one and isomeric‐5‐one derivatives are discussed with the aid of defocused metastable spectra and exact mass measurements. The compounds are shown to be very stable to electron impact and ring contrac
