A novel, straightforward synthesis of enantiomerically pure 2,6-disubstituted morpholines has been developed. The ring-opening of epoxides with TsNHBoc under solid−liquid phase transfer catalysis conditions occurred with N → O migration of the Boc group, affording an intermediate carbonate that has been easily transformed to morpholines.
已经开发了对映体纯的2,6-二取代的吗啉的新颖,直接的合成。在固液相转移催化条件下,TsNHBoc与环氧化物的开环是由Boc基团的N→O迁移引起的,提供了一种易于转化为吗啉的中间体碳酸盐。
