Article abstract of DOI:10.1246/cl.1987.491

The aldol reaction of silyl enol ethers with acetals or aldehydes, and the Michael reaction of silyl enol ethrs with α,β-unsaturated ketones are efficiently catalyzed by the combined use of trityl chloride and tin(II) chloride under extremly mild conditio
