- Studies in large ring compounds: Synthesis of some new morphanthrindines and diazocines
-
A novel method for the synthesis of 2 or 3-substituted 5,6-dihydro-6,11-dioxo-morphanthridines (2) involving the cyclisation of anilinic acid (1) with PPA/AcOH has been developed. A new heterocyclic system, 2 or 3-Substituted 5,6,11,12-tetrahydrodibenzo[b, f] [1,4]diazocine-6,11-diones(4) has been synthesized with excellent yields.
