以3-噻吩甲醛和氨基乙醛缩二甲醇为原料, 经亲核加成、还原、取代、成环、甲酰化反应, 得到2-醛基噻吩并[3,2-c]吡啶(4), 然后与亚磷酸酯、芳香胺发生类Mannich反应得到一系列新型含有噻吩并[3,2-c]吡啶环的α-氨基膦酸酯类衍生物6a6p. 所有目标化合物的结构均经1H NMR, 13C NMR, 31P NMR, IR和MS确证. 初步的生物活性测定试验表明, 在50 ug/mL浓度下, 大部分目标化合物对食管癌细胞(EC109)、人体肝癌细胞(HepG2)表现出较好的抑癌活性, 其中化合物6k6o对人体肝癌细胞的抑制率超过90%.

A series of novel α-aminophosphonate derivatives containing thieno[3,2-c]pyridine (6a6p), which have never been reported in literature, were synthesized from thieno[3,2-c]pyridine-2-carbaldehyde, phosphate ester and aromatic amine by the Mannich-type reaction. Thieno[3,2-c]pyridine-2-carbaldehyde (4) was produced via nucleophilic addition reaction, reduction, substitution reaction, cyclization, formylation using 3-thiophene formaldehyde and 2,2-dimethoxyethanamine as the starting material. The structures of all compounds have been confirmed by 1H NMR, 13C NMR, 31P NMR, IR and MS techniques. The preliminary results of biological tests indicated that most of the title compounds exhibit relatively good anticancer activity against EC109, HepG2 at the concentration of 50 μg/mL, especially compounds 6k and 6o have more than 90% inhibitory rate against HepG2
