Copper(II)-catalyzed Formation of 1,3-Dioxolanes from Oxiranes

However,these methodologies limit the general synthesis of variousdioxolanes due to the low yields, relatively long reactiontimes, the use of large amounts of catalyst, and the lack ofreactivity depending on the types of oxiranes. In the courseof our mechanistic studies on catalytic reactions of Cu(II),imines, and ethyl diazoacetate (EDA) in acetone,
