4-Aminocyclopenta-, 4-aminocyclohexa-, and 4-aminocycloheptathieno[2,3-b]pyridines were synthesized in very low overall yield by four-step procedures starting from bis(2-thienylammonium) hexachlorostannate(IV) and 2-hydroxymethylenecyclopentanone, 2-methoxymethylenecyclohexanone, and 2-hydroxymethylenecycloheptanone, respectively.
从双(2-噻吩铵)六氯锡酸酯(IV)和2-羟基亚甲基环戊酮开始的四步合成方法以极低的总收率合成了4-氨基环戊-,4-氨基环己-和4-氨基环庚二酮[2,3- b ]吡啶,2-甲氧基亚甲基环己酮和2-羟基亚甲基环庚酮。
