The synthesis of the title compounds 5H, 11H-pyrido[2′,3′:2,3]thiopyrano[4,3-b]indoles was accomplished by the Fischer indole cyclization of some 2,3-dihydrothiopyrano[2,3-b]pyridin-4(4H)-one phenylhydrazones and 7-methyl-2,3-dihydrothiopyrano[2,3-b]pyridin-4(4H)-one phenylhydrazones. The synthesis of the new 2,3-dihydrothiopyrano[2,3-b]pyridin-4(4H)-one, which was used as one of the starting compounds
标题化合物5 H,11 H-吡啶并[2',3':2,3]硫代吡喃并[4,3- b ]吲哚的合成是通过将2,3-二氢硫代吡喃并[2, 3 - b ]吡啶-4(4 H)-一苯hydr和7-甲基-2,3-二氢硫代吡喃并[2,3- b ]吡啶-4(4 H)-一苯hydr。还描述了用作起始化合物之一的新的2,3-二氢硫代吡喃并[2,3- b ]吡啶-4(4 H)-one的合成。
