Tandem Hydroformylation/Aldol Addition of Silyl Enol Ethers Bearing Remote Olefinic Functionalities
摘要:
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.
