Recently chloranil was employed as cyclising
agent for the synthesis of dissymmetric TPDOs, however, the product was obtained indirectly through bisphenoxy or phenoxazine tricyclic intermediate [14, 15] instead of dianilide intermediate.
So my research is in trying to develop a general method for cyclising
peptides which will help others in the future in their synthesis of drug targets.
In another experiment the same group synthesized a series of 2-substituted 4H-3,1- benzoxazinones and 2,3-disubstituted 3H-quinazolin- 4-one under mild conditions using triphenyl phosphite and pyridine as cyclising
