Rhodium(I) complex catalysed hydroformylation of unsaturated silyl enol ethers leads to products of an intramolecular aldol addition in a one-pot procedure. Thus beta,gamma- or gamma,delta-unsaturated silyl enol ethers undergo tandem hydroformylation/Mukaiyama aldol reaction to form cyclic O-silylated aldol adducts with high selectivity and good yields.

Novel rhodium(I) complex catalysed tandemhydroformylation/aldolreactions of a β,γ-unsaturated ketone 1 or its silyl enol ethers 4 in a one-pot procedure are presented to give varying cyclisation products depending on the reaction conditions.
