Abstract

Abstract Pauson–Khand reactions of functionalized allenes with different alkynes give cyclopentenones with generally high regio-and stereoselectivities. The allenes react through their external double bonds, giving cyclopentenones with exocyclic double bond at their β positions and predominantly with E stereochemistry. Some intramolecular reactions with allenynes connected through aromatic rings are described. These give the corresponding ...
