Intramolecular PIFA-mediated alkyne amidation and carboxylation reaction.

Imanol Tellitu1, Sonia Serna, M Teresa Herrero, Isabel Moreno, Esther Domínguez, Raul SanMartin.   

Abstract

The hypervalent iodine reagent PIFA promotes the intramolecular electrophilic cyclization of easily accessible alkynylamides and alkynyl carboxylic acids, leading to the formation of pyrrolidinone and lactone skeletons, respectively, in a very efficient way. A synthetic study and a mechanistic proposal for these transformations are presented.
