regioselective CC coupling has been developed. This is a Cu (II) catalyzed cross dehydrogenative coupling (CDC) involving enamino-ketones of benzyl amines and di-alkyl acetylenedicarboxylate, followed by cyclization by primary amines. TBHP (tert-butyl hydroperoxide) has been used as the oxidant to promote the coupling protocol. This synthetic route principally demonstrates the scope of CDC reaction and also

A multicomponent green methodology was developed to synthesize 3-hydroxy-2-pyrrolidinones under admicellar catalysis by TiO2 nano-particles at room temperature (30 degrees C). TiO2 nano-particles in aqueous CTAB solution promote the formation of admicelles and the reaction occurs in admicellar environment. The methodology was successfully applied to synthesize a variety of 3-hydroxy-2-pyrrolidinones and 3'-hydroxyspiro-2'-pyrrolidinone derivatives. (C) 2013 Elsevier Ltd. All rights reserved.
