chlorobenzaldehyde to yield the benzylidene derivative 2 which underwent Michael addition reacting with cyanothioacetamide in methanolic sodium methoxide solution to give the thienoquinoline 3. Compound 3 was reacted with α- halo compounds to obtain the substituted thio intermediates 4a-f, which upon treatment with sodium ethoxide produce the dithienoquinoline derivatives 5a-f. Thienopyrimidothienoquinoline

compounds are obtained by chemical synthesis. In this context, the use of fluorinated building blocks is one of the most prevalent strategies to introduce fluorine atoms into organic molecules.10 This approach requires small fluorinated molecules, stable and easily available in large scale. Among them, fluorinated imines are one of the most popular building blocks for the synthesis of fluorinated nitrogen-containing
