New Schiff's Base and 2-Azetidinone Derivatives of 3-Benzo[4,5]imidazo[2,1-b]thiazol-3-yl-chromen-2-one by Vilsmeier–Haack Formylation
摘要:
A new Schiff's base and 2-azetidinone derivatives obtained via the corresponding 3-benzo [4,5] imidazo [2,1-b] thiazol-3-yl-chromen-2-one by Vilsmeier-Haack formylation scaffold is described. Our design is aimed at obtaining new triheterocyclic and tetraheterocyclic derivatives.
