Synthesis of heterocyclic systems by transition-metal-catalyzed cyclization-migration reactions - A diversity-oriented strategy for the construction of spirocyclic 3(2H)-furanones and 3-pyrrolones
Two platinum(II)-catalyzed heterocyclization-migration reactions that provide five-membered heterocycle products are described. With 5 mol-% of PtCl2 as a catalyst, 2-alkynyl-2-hydroxy carbonyl compounds 1 are converted into 3(2H)-furanones 2 a

Gold(III)- and platinum(II)-catalyzed domino reaction consisting of heterocyclization and 1,2-migration: Efficient synthesis of highly substituted 3(2H)-furanones
(Chemical Equation Presented) PtCl2-catalyzed alkyne activation initiates a domino reaction, in which a heterocyclization is followed by a 1,2-alkyl migration, for the construction of a variety of substituted 3(2H)-furanones. This stereospecifi
