The Synthesis of 1H-Pyrazolo[3,4-b]quinoxaline Derivatives Oriented towards Modification of Carbocyclic Ring in the Parent Skeleton
Katarzyna Wojtasik , Andrzej Danel
AbstractPalladium catalyzed aminoarylation reactions are widely used to create new C−N bonds. It has been proved that the method of synthesis of 1H ‐pyrazolo[3,4‐b ]quinoxaline derivatives (PQX), consisting of the reductive cyclization of the corresponding pyrazole derivative, is the most universal method of PQX synthesis among the known and is regiospecific. The obtained x‐chloro‐1‐methyl‐3‐phenyl‐1H ‐pyrazolo[3,4‐b ]quinoxaline isomers were starting materials for the synthesis of N,N ‐diethylamine derivatives. The position differentiation of these substituents strongly impact the emissive properties of the final compounds.
