  Regioselective Synthesis of 2H‐Benzothiopyrano[3,2‐c]quinolin‐7(8H)‐ones by Tri‐n‐butyltinhydride–Mediated Radical Cyclization

  摘要：

  A number of hitherto unreported2H-benzothiopyrano[3,2-c]quinolin-7(8H)-ones have been regioselectively synthesized in 90-96% yield by tri-n-butyltinhydride-AIBN-mediated radical cyclization from 4-(20-bromothioarylmethyl)1-methylquinolin- 2(1H)-ones and their corresponding sulfones. 4-(20-Bromothioarylmethyl) quinolin-2(1H)-ones were in turn prepared from 4-bromomethylquinolin2(1H)-one and o-bromothiophenols by refluxing in acetone in the presence of anhydrous K2CO3. These were converted to the corresponding sulfones by oxidation with two equivalents of m-CPBA in refluxing dichloromethane for 1 h.
