Abstract

A variety of perfluoroalkyl-substituted γ-spiroiminolactones have been synthesized via a one-pot, three-component cascade reaction in which isocyanides, methyl perfluoroalk-2-ynoates and 1,2-diketones undergo highly regioselective Michael addition, nucleophilic addition and cyclization. This reaction has the advantages of good to excellent chemical yields, operationally simple procedure, and short reaction times.

Key words

spiroiminolactones - perfluoroalkyl-substituted - isocyanide - multicomponent reaction - methyl perfluoroalk-2-ynoate
