  • Title: Synthesis of 3,4-disubstituted maleimides by selective cross-coupling reactions using indium organometallics.
    Author: Bouissane L, Pérez Sestelo J, Sarandeses LA.
    Journal: Org Lett; 2009 Mar 19; 11(6):1285-8. PubMed ID: 19220015.
    Abstract:
    Unsymmetrical 3,4-disubstituted maleimides have been synthesized by palladium-catalyzed cross-coupling reactions of indium organometallics with 3,4-dihalomaleimides. The synthesis was performed by stepwise or sequential one-pot palladium-catalyzed cross-coupling reactions with various triorganoindium reagents. This method was used to prepare a wide variety of alkyl, aryl, heteroaryl, and alkynyl 3,4-disubstituted maleimides in good yields and with high selectivity and atom economy.
