Pyrrolo[1,2-f]phenanthridines were prepared in good yields by the diazotization in acetic acid of the amines la,b and subsequent treatment with hypophosphorousacid. The necessity for hypophosphorousacid in the reaction was demonstrated.
通过将胺1a,1b在乙酸中重氮化并随后用次磷酸处理,可以高收率制备吡咯并[1,2- f ]菲啶。证明了反应中次磷酸的必要性。
