According to the synthetic methods study of the quinolones, it is found that the synthetic method of parent ring is of wide use by the condensation from α-substituted aryl formyl-β-substituted aminoacrylic acid and the inner molecular nucleophilic substitution reaction, which is almost suitable for the quinolones preparation of different rings or different substituted groups in 〓-position.
然后,对其合成方法进行了归纳,发现:由α-取代芳甲酰基-β-取代氨基丙烯酸缩合,经分子内亲核取代反应形成喹诺酮母环的合成方法用途非常广,几乎适用于所有不同环系或〓-位是不同取代基的喹诺酮类衍生物的制备。

Simultaneously we prepared benzimidazolines with two methods by the reducton of benzimidazolium salts with NaBH_4 and Grignard addition with benzimidazolium salts. Thus we provided a new biomimic synthetic method for 9 kind of tetrahydro-β-carboline starting from carboxylic aicd and halid. A convenient synthetic method for preparing tetrahydro-β-carboline was provided.
本文以1,3-二甲基苯并咪唑碘盐和2-取代的1,3-二甲基苯并咪唑碘盐为原料,采用了NaBH_4还原和Grignard试剂加成两种方法,制备了9种1,3-二甲基苯并咪唑烷和2-取代的1,3-二甲基苯并咪唑烷作为四氢叶酸辅酶一碳单元转移新模型,在酸性条件下,以色胺作为接受一碳转移的亲核试剂,完成9种四氢-β-咔啉类化合物的新合成方法研究。

A general novel synthetic method to Symmetrically or unsymmetrically 2,3,6,7- substituted thieno[2,3-d:5,4-d\']dipyrimidine-4,5(3H,6H)-diones and 2-substituted benzothieno[3,2-d] pyrimidin-4(3H)-dione by utilizing aza-Wittig reaction was proposed firstly. This synthetic method has the advantage of easily accessible starting material, mild condition and good yields.
具体研究内容如下:1、首次研究了应用aza-Wittig反应方法合成2,3,6,7-对称与不对称四取代噻吩并[2,3-d;5,4-d\']双嘧啶-4,5(3H,6H)-二酮以及2-取代苯并噻吩并[3,2-d]嘧啶-4(3H)-酮衍生物的通用新方法,该方法原料易得,条件温和,收率较高。
