微积分理论中一个遗留的古典问题

Asymmetric Diels-Alder Reaction of 3-(2-Butenoyl) -1,3-Oxazolidin-2-One with Cyclopentadiene Using a Chiral Titanium Catalyst

通过构造反例的规律找出了累次极限与重极限的关系，填补了微积分学在此的空白，解决了遗留的古典问题．

By the use of the titanium catalyst which was prepared by the alkoxy exchange between dibromodiisopropoxy-titanium (Ⅳ) and a chiral 1,4-diol derived from (2R, 3R)-tartrate, the reaction of 3-(2-butenoyl)-1,3-oxazolidin-2-one with cyclopentadiene was discussed.
