RESUMEN
The moiety of 4-imidazolidinone is an important structural motif in organic synthesis and medicinal chemistry. We present the synthesis of 4-imidazolidinones from various diamides with ethynyl benziodoxolones through double Michael-type addition, which is an unprecedented reaction mode for hypervalent alkynyl iodine compounds. cis-2,5-Disubstituted 4-imidazolidinones were diastereoselectively synthesized from amino acid derived diamides. Having derivatized the 4-imidazolidinones, several control experiments and density functional theory calculations were conducted to realize mechanistic insight.
