非共轭噻吩基四炔衍生物 1-3 被制备为构建茚并噻吩酮衍生物的新型结构单元。 1-3的氧化，随后相应酮衍生物13-15的环芳构化顺利进行，以良好的收率得到茚并噻吩酮衍生物16-21。 (C) 2005 Elsevier Ltd. 保留所有权利。
Non-conjugated thienyl tetrayne derivatives 1-3 are prepared as novel building block for the construction of indenothiophenone derivatives. Oxidation of 1-3, followed by cycloaromatization of the corresponding ketone derivatives 13-15 proceeds smoothly to afford indenothiophenone derivatives 16-21 in good yields. (C) 2005 Elsevier Ltd.
