摘要

The syntheses of hexa and tetra-propargylated pyrido[4',3':4,5] thieno[2,3-d]-pyrido[4''', 3''': 4 '', 5 ''] thieno[2 '', 3 '': 4', 5'] pyrimido[1',2':4,5] pyrazino[1,2-a]pyrimidines, are described by the reaction of hepta-annulated heterocyclic systems with propargyl bromide. Multiple alkyne-azide click reaction of these alkyne cores established them as a scaffold for six and four functionalised 1,2,3-triazoles and attached biomolecules.
