Synthesis and Properties of α-Bromomethyl-Substituted β-Ethoxyvinyl Polyfluoroalkyl Ketones
摘要:
An efficient and practical method for the synthesis of -bromomethyl-substituted -alkoxyvinyl polyfluoroalkyl ketones is reported. These highly functionalized -bromomethyl enones easily react with various nucleophiles and binucleophiles affording a wide variety of new functionalized enones and heterocyclic systems that are perspective starting materials for the synthesis of compounds with potentially high biological and pharmacological activity.

CDCl3. Acid treatment of the latter compounds 8 led to the hitherto unknown ethyl 5-polyfluoroalkyl-pyrrole-2-carboxylates 11 by elimination of formic acid. Catalytic hydrogenation of pyrrole 11a was used for the synthesis of earlier unknown 5-trifluoromethyl proline 16.
