Abstract
3,5'-Di-O-mesylthymidine 4a (DMST) on reaction with secondary amines u ndergoes hitherto unknown ''one-pot-two-steps'' transformation to prod uce 2,3'-O-anhydro-5'-deoxy-5'-alkylaminothymidines 5a-h. Most of the amines used, irrespective of their basicities showed remarkable select ivity towards the 5'-substitution over the 2,3'-O-anhydro ring formati on. Compounds 5a-h could be used as intermediates for the synthesis of a variety of ,5'-dideoxy-3'-substituted-5'-alkylaminothymidines of th e type 9, 10a-b, 11.
