摘要：

Structural features of ligands and substrates affecting enantioselectivity in vanadium (V)-catalyzed epoxidation of allylic alcohols were investigated. For the hydroxamic acid ligands derived from arylhydroxylamines, 2-aryl-substituted allylic alcohols emerged as the best substrates furnishing good level of enantioselectivity.
