Action of hydrazines on ketoaldehydephosphonates: Synthesis of β-phosphocycloalcanepyrazoles
Written by sctunisie no commentsA variety of ketoaldehydphosphonates 2 have been prepared by reaction of γ-ketophosphonates 1 with ethylformate in basic conditions. On reaction with hydrazines, compounds 2 lead to β-phosphocycloalcanepyrazoles 3. The structure of all obtained products was determined on the basis of their IR and NMR data.
