摘要：
Prepared by a high yield, chromatography-free route, "oligosalen" exists as a mixture of dimer, trimer, and tetramer (see picture). Derived catalyst systems display remarkable activity and selectivity in the asymmetric ring-opening of epoxides, with turnover numbers exceeding 100000 in some cases.
