摘要:一种改进的路线2-取代的6-羟基-[3 H ^]-嘧啶-4-酮4和2-取代的4,6-二氯嘧啶5报道.不使用剧毒反应物,就可以方便地在一锅合成中以1摩尔规模制备化合物4,平均收率可达80%.通常使用少量原料制备的4,6-二氯嘧啶5的平均收率为80%,最多可使用80 G起始原料.4氯化的机理是第一次进行计算研究.结果表明,磷酰氯的氯化反应以交替的磷酸化-氯化方式(途径1)进行,这比以两次磷酸化开始的顺序更可取.本文所述的研究的4,6-二氯嘧啶与二氯磷酸形成强络合物,但与盐酸形成弱络合物(在后处理期间反应生成).后面这些配合物解释了在后处理过程中使用碳酸钠水溶液的必要性.为了防止在中间体或最终的二氯嘧啶和未反应的羟基嘧啶之间形成嘧啶鎓盐,可以用强酸(例如二氯磷酸)使后者失活,从而进行氯化反应,但阻止形成盐.

权利人:KUMIAI CHEMICAL INDUSTRY CO
摘要:An object of the present invention is to identify an enzyme having activity of synthesizing dihydrotentoxin that is a tentoxin precursor and an enzyme having activity of synthesizing tentoxin using dihydrotentoxin as a substrate. The present invention concerns a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 16 and having activity of nonribosomal peptide synthesis of dihydrotentoxin and a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 18 and having activity of converting dihydrotentoxin to tentoxin.
