Benzothiopyrano[2,3-b]indoles were prepared by the cyclization of 1,3-dihydroindole-2-thiones with various dienophiles. The 1,3-dihydroindole-2-thiones were readily synthesized by the reaction of oxindole with P 2 S 5 followed by a piperidine-mediated condensation of the resulting thioindole with a suitable aromatic aldehyde.
苯并噻吩并[2,3-b]吲哚通过1,3-二氢吲哚-2-硫酮与各种亲双烯体的环化制备。1,3-二氢吲哚-2-硫酮很容易通过羟吲哚与P 2 S 5 的反应合成,然后由哌啶介导的所得硫代吲哚与合适的芳族醛缩合。
