as key intermediates, is described. The key step involves an IMDAF reaction with an excellent stereocontrol. This novel synthetic route provides new cycloadducts as useful scaffolds for Ergot alkaloids synthesis.
描述了一种简单而通用的方法,该方法使用2-取代的3,7-二硝基-11-氧杂三环十一烷基-9-烯作为关键中间体来制备各种麦角灵或西麦角灵骨架。关键步骤涉及具有出色立体控制的IMDAF反应。这种新颖的合成途径提供了新的环加合物作为麦角生物碱合成的有用支架。
