Peculiarities of cyclization of ethyl 2-ethoxymethylene-3-oxo-3-(polyfl uoroalkyl)propionates with 3-amino-5-hydroxypyrazoleMarina V. Goryaeva, Yanina V. Burgart, Viktor I. Saloutin

� Ethyl 2-ethoxymethylene-3-oxo-3-(polyfl uoroalkyl)propionates react with 3-amino-5-hydroxypyrazole to give dihydropyrazolo[1,5-a]pyrimidines. � Dihydropyrazolo[1,5-a]pyrimidines undergo recyclization to form pyrazolo[3,4-b]pyridines and are dehydrated to pyrazolo[1,5-a]pyrimidines. � Non-fl uorinated 2-ethoxymethylene-3-oxo esters in the reactions with 3-amino-5-hydroxypyrazole form only pyrazolo[1,5-a]pyrimidines.
