imines with sodium borohydride under reflux condition leads to an intramolecular cyclization through C–Br and C–H coupling without any transition-metal catalyst, furnishing 5,6-dihydrophenanthridine and phenanthridine derivatives.
2,6-二取代-1-溴芳基亚胺与硼氢化钠在回流条件下的反应导致分子内环化反应通过C-Br和C-H偶联而无需任何过渡金属催化剂,从而提供5,6-二氢菲啶和菲啶衍生物。
