8-Aza-5,7-dimethyl-2-trifluoromethylchromone reacts with alkyl mercaptoacetates to give pyrido derivatives of 2-oxa-7-thiabicyclo[3.2.1]octane, which undergo the reductive ring-opening to sulfanyl acetates. The latter compounds are useful CF3-containing building blocks for the preparation of a variety of 2-pyridone derivatives.
