资源简介：
Access to chiral polysubstituted cyclobutanones by [2 + 2]-cycloaddition of ketenes with chiral acyclic enol ethers is reported. A wide variety of easily accessible di- and monosubstituted ketenes were found to react with a very high degree of stereoselectivity with chiral, Stericol derived, acyclic enol ethers. This combination of simple reagents provides straightforward entry to highly substituted enantioenriched cyclobutanones.
