The new compounds 2-[4-(6-cyanobenzothiazol-2-yl)phenyl]-5-(6-cyano-benzothiazol-2-yl)furan (6a) and 2-[4-(6-Cyanobenzothiazol-2-yl)phenyl]-5-(6-cyano-benzothiazol-2-yl)thiophene (6b) were synthesized by multi-step reactions from the corresponding 2-furan and 2-thiophene carboxaldehydes (route A), as well as from 2-furan and 2- thiophene carboxylic acids (route B). Route B involves one less step than route A, but the overall yields of the reactions are considerably lower.
新化合物2-[4-(6-氰基苯并噻唑-2-基)苯基]-5-(6-氰基苯并噻唑-2-基)呋喃(6a)和2-[4-(6-氰基苯并噻唑-2-基)苯基]-5-(6-氰基苯并噻唑-2-基)噻吩(6b)通过多步反应,分别从相应的2-呋喃和2-噻吩醛(路线A)以及2-呋喃和2-噻吩羧酸(路线B)合成得到。路线B相比路线A少了一步,但反应的总产率明显较低。
