synthesized to investigate their potential CNS activity. Synthesis of the desired ring system was effected by condensation of 2,3-diaminopyridine (3) with methyl tetrahydro-4-oxo-3-thiophenecarboxylate (4). Structural assignment of the major condensation product 5 was determined by comparison of 1H nmr absorptions of 5 with those of related methyl lactam derivatives 11 and 14. A discussion of the possible
合成了Pyrido [3,2- b ] thieno [3,4- e ] [1,4]二氮杂((1a-d)以研究其潜在的CNS活性。所需的环体系的合成分别将2,3-二氨基吡啶(缩合实现3)与甲基四氢-4-氧代-3-噻吩(4)。主要缩合产物的结构分配5用的比较确定1个NMR的吸收ħ 5与那些相关的甲基内酰胺衍生物的11和14的可能机制导致的讨论5优先于同分异构的内酰胺6被表达。1a-d的生物学评估没有发现有趣的特性。
