A novel and efficient synthesis of 3,3-disubstituted indol-2-ones via Passerini three-component reactions in the presence of 4 ? molecular sieves

Esmaeili, Abbas Ali,Amini Ghalandarabad, Saeid,Jannati, Saeideh

, p. 406 - 408 (2013/02/23)

The Passerini coupling of cyclohexylisocyanide with isatins and carboxylic acids in the presence of 4 ? molecular sieves is described. This process offers a highly efficient and atom-economic access to 3-acyloxy-3-carboxamido-1, 3-dihydro-2H-indol-2-ones in high to excellent yields.
