Abstract
Trans (+) and (-) 6-alkoxy-5-bromo-5,6 dihydrothymidine and trans (+) and (-) 6-alkoyloxy-5-bromo-5,6-dihydrothymidine compounds have been prepared. The synthesis of these substances (alkoxy : methoxy, ethoxy, butyloxy and isoamyloxy and alkoyloxy : acetoxy and bensovloxy) is described. Diastereoisomers of all products have been isolated by thin layer chromatography and their spectroscopic properties (IR, UV, NMR, mass spectrometry) studied. These compounds have been shown to be competitive inhibitors of Ehrlich's ascites cells thymidine kinase with respect ot thymidine.
