The synthesis of new pyrido[3′,2′:5,6]thiopyrano[3,2-b]indol-5(6H)-ones was accomplished by the Fischer-indole cyclization of some 2,3-dihydro-3-phenylhydrazonothiopyrano[2,3-b]pyridin-4(4H)-ones, obtained from the 2,3-dihydro-3-hydroxymethylenethiopyrano[2,3-b]pyridin-4(4H)-one, by the Japp-Klingemann reaction.
新的吡啶并[3',2':5,6]硫代吡喃并[3,2 - b ]吲哚-5(6 H)-的合成是通过一些2,3-二氢-3的费-吲哚环化完成的由2,3-二氢-3-羟基亚甲基硫代吡喃并[2,3 - b ]吡啶-4(4 H)-一获得的-苯基肼基硫代吡喃并[ 2,3- b ]吡啶-4(4 H)-一Japp-Klingemann反应。
