mediated glycosylations wherein 3,3-difluoro-3H-indol-2-yl (OFox) imidates were found to be key intermediates. Both the in situ synthesis from the corresponding glycosyl bromides and activation of the OFox imidates could be conducted in a regenerative fashion. Herein, we extend this study with the main focus on the synthesis of various OFox imidates and their investigation as glycosyl donors for chemical
以前,我们交流了3,3-二氟己二酮(HOFox)介导的糖基化作用,其中发现3,3-二氟-3 H-吲哚-2-基(OFox)酰亚胺化是关键中间体。无论是在原位由相应的糖基溴化物和亚胺酸酯OFox活化合成可以在再生的方式进行。在这里,我们扩展了这项研究,主要侧重于各种OFox酰亚胺的合成及其作为化学1,2-顺式和1,2-反式糖基化的糖基供体的研究。
