novel diastereofacial differentiating Cu-catalyzed Michael addition–cyclization reaction, which provided access to a chiral pyrroline in a highly stereoselective manner. The chiral pyrroline was converted to (−)-kainic acid via the stereoselective 1,4-reduction of the pyrroline double bond in three steps.
已开发出一种简短的(-)-海藻酸全合成方法,该方法涉及一种新的非对面分化型Cu催化的Michael加成-环化反应,该反应以高度立体选择性的方式提供了手性吡咯啉的通道。手性吡咯啉在三个步骤中通过吡咯啉双键的立体选择性1,4-还原而转化为(-)-海藻酸。
