A new one-pot synthetic strategy is described for the synthesis of enantiomerically pure cis-3,5-disubstituted morpholines and 3,6-disubstituted 1,4-oxazepanes via tandem aziridine/epoxide ring opening sequences. This new strategy describes how epoxy alcohols could act as both a nucleophile and an electrophile in a tandem fashion and undergo intermolecular regioselective ring opening of chiral aziridines
描述了一种新的一锅合成策略,用于通过串联合成对映体纯的顺式-3,5-二取代的吗啉和3,6-二取代的1,4-恶唑酮。氮丙啶/环氧开环顺序。该新策略描述了环氧醇如何同时充当亲核试剂和亲电子试剂,并首次经历手性氮丙啶的分子间区域选择性开环。
