Abstract

Recently, Cha and co-workers published a method that might circumvent these difficulties. They extended the Kulinkovich cyclopropanation reaction 6 to imides in such a way that N,O-acetals were generated that might serve as precursors of tertiary N-acyliminium ions. 7 In this paper, we describe the application of this methodology to explore the synthetic utility of such cationic intermediates in inter- and intramolecular reactions and extend it to the synthesis of the ...
