A versatile and highly stereoselective borylative cyclization to generate polyfunctionalized γ-lactams has been developed. The stereoselective synthesis of these key ring systems is crucial due to their ubiquity in natural products. We report the diastero- and enantioselective construction of di- and trisubstituted γ-lactam cores, with examples containing an enantioenriched quaternary carbon.
已经开发了一种通用且高度立体选择性的硼化环化反应以生成多官能化的γ-内酰胺。这些键环系统的立体选择性合成至关重要,因为它们在天然产物中无处不在。我们报道了二取代和三取代的γ-内酰胺核的非对映体和对映体选择性结构,并举例说明了富含对映体的季碳。
