A series of alkyl thiazole-2-carboxylates containing a range of substituents at the 4- and 5-positions has been prepared.Solutions of these esters (mostly new compounds) show well resolved doublets in the i.r.C=O region which arise from rotational isomers.The higher wavenumber components are assigned to the more polar carbonyl O,S-anti-s-trans-rotamers and the lower wavenumber components to the carbonyl O,S-syn-s-trans-forms.Small, but systematic, differences between the methyl esters are noted.
