ChemInform Abstract
The Vinylogoushemiacetals (I) react with a series of silyl enol ethers such as (II), (IV), (VI), (XI), (XIV) and (XVII) to give the products shown in the scheme. Some of these products are cyclizned according to method B) to give cyclopropanes [(IX) from (IIIb) and (X) from (Va)] or cyclohexanones. Further examples for the above reactions are described.
