An original and rapid domino reaction for access to oxazolidin-4-ones is presented. Simply by heating α-bromoamido alcohol in the presence of KNaCO3 and water with readily prepared Michael acceptors, an unprecedented molecular rearrangement is generated. This new methodology enables the hitherto unreported synthesis of functionalized oxazolidin-4-ones. The process was proved to be compatible with a
提出了一种原始的快速多米诺骨牌反应来获得
恶唑烷丁-4-酮。只需在KNaCO 3和存在下的
水与易于制备的Michael受体一起加热α-
溴酰胺醇,即可产生前所未有的分子重排。这种新方法使功能性的
恶唑烷丁-4-酮迄今未见报道。事实证明,该方法可与多种底物兼容,并具有很高的区域选择性。
