sequence. The synthetically interesting and medicinally important pentacyclic butyrolactam-fused indoloquinolizidines can be efficiently constructed in a highly stereocontrolled manner. Importantly, the chemistry described herein provides a general catalytic method for the enantioselective synthesis of butyrolactam-incorporated chemical entities.
已经在有机催化一锅Michael / Pictet-Spengler序列中探索了α-氧代-γ-丁内酰胺的环境反应性。可以以高度立体可控的方式有效地构建合成上有趣且对医学有重要意义的五环丁内酰胺融合的吲哚并喹喔啉。重要的是,本文所述的化学方法为掺入丁内酰胺的化学实体的对映选择性合成提供了一种通用的催化方法。
