Özet:

A new methodology was developed for the synthesis of dipyrromethane and diazepine

derivatives. In the first section of this thesis, synthesis of various dipyrromethanes

from aromatic aldehydes was carried out. Dipyrromethanes were used as starting

materials for the next step. In the second part of the study, introduction of a propargyl

group to nitrogen atom to one of pyrrole units of dipyrromethane gave the expected

mono-propargylated compounds which were the key compounds for further

cyclization reactions. Base-supported cyclization resulted in the formation of the target

compounds, new diazepine derivatives, via metal-free 7-exo-dig cyclization.
