Fluoro organics: synthesis of novel fluorinated 4-oxo-4H-pyrido[3′,2′:4,5]furo[3,2-d]-1,3-oxazines and their reactions
摘要:
Novel fluorinated 4-oxo-4H-pyrido[3',2':4,5]furo[3,2-d]-1,3-oxazines have been synthesised from 2-carbethoxy-3-amino-4-trifluoromethyl-6-aryl-substituted furo[2,3-b] pyridines via intermediates such as 2-carboxy-3-amino-4-trifluoromethyl-6-aryl-substituedfuro[2,3-b]pyridines. and 2-carboxy-3-trifluoroacetylamino-4-trifluoromethyl-6-aryl-substituted furo [2,3-b]pyridines. The CF3 group induces changes in the reactivity in the molecule and the consequent regioselective attack of nucleophiles on the oxazine ring have been studied and utilized for mechanistic interpretation.
