## Abstract The synthesis of new pyrido[3′,2′:5,6]thiopyrano[3,2‐__b__]indol‐5(6__H__)‐ones was accomplished by the Fischer‐indole cyclization of some 2,3‐dihydro‐3‐phenylhydrazonothiopyrano[2,3‐__b__]pyridin‐4(4__H__)‐ones, obtained from the 2,3‐dihydro‐3‐hydroxymethylenethiopyrano[2,3‐__b__]pyrid
