Divergent reactivity is uncovered in the homologation of arylcyclobutanones with trimethylsilyldiazomethane. With Sc(OTf)3 as catalyst, enolsilanes are obtained with a high preference for methylene migration. By contrast, Sc(hfac)3 g
Metal mediated one-pot synthesis of cyclopentanones from allyl vinyl esters or diallyl ethers via tandem Claisen rearrangement and hydroacylation

Cyclopentanones 3 and 7 are generated in a one-pot procedure from allyl vinyl ethers 1 and diallyl ethers 4, respectively. The conversion is carried out in the presence of RhCl(cod)(dppe) or RuCl2(PPh3)3 at elevated temper
