The synthesis of enantiomers of 6-tert-butyl-6-methylmorpholine-2,5-dione (3) using Wang resin supported 2-
chloro- or 2-bromo- pyridinium triflate is described. The applied methodology could be considered as an interesting alternative
to “classical” one and enables the synthesis of 6-tert-butyl-6-methylmorpholine-2,5-dione with higher yields and
the isolation of product (3) is significantly easier.

吗啉-2,5-二酮(3)对映体的方法。所应用的方法可被视为 "经典 "方法的一种有趣的替代方法,它能以更高的产率合成 6-叔丁基-6-甲基
吗啉-2,5-二酮,而且产品 (3) 的分离也明显更容易。
