(5a) was prepared by a novel synthetic route involving the rearrangement of (±)-(Z)-1,10a-dihydropyrrolo[1,2-b]isoquinoline-3,10(2H,5H)-dione oxime to afford 1,4-dihydrobenzo[c]-1,5-naphthyridin-2(3H)-one, which was reduced to 5a. The cholinomimetic activity observed with 5a prompted the synthesis and biological evaluation of additional analogues.
1,2,3,4-四氢苯并[ c ] -1,5-萘啶(5a)是通过涉及(±)-(Z)-1,10a-二氢吡咯并[1,2- b ]异喹啉-3,10(2 H,5 H)-二酮肟制得1,4-二氢苯并[ c ] -1,5-萘啶-2(3 H)-一,还原为5a。用5a观察到的拟胆碱活性促使其他类似物的合成和生物学评估。
