A Tandem Cyclization-Onium Ylide Rearrangement-Cycloaddition Sequence for the Synthesis of Benzo-Substituted Cyclopentenones

A new annulation sequence leading to benzo-substituted cyclopentenones is effected by treating o-alkynyl-substituted α-diazoacetophenones containing tethered heteroatoms with Rh(II) carboxylates.The reaction involves addition of the initially formed keto

Rhodium(II)-Catalyzed Cyclization Reactions of Alkynyl-Substituted α-Diazo Ketones

Treatment of several o-alkynyl-substituted α-diazoacetophenone derivatives with rhodium(II) carboxylates results in the formation of substituted indenones.The simplest mechanism accounting for the results involves addition of a rhodium-stabilized carbenoi
