    Application of directed metallation in synthesis. Part 3: Studies in the synthesis of (±)-semivioxanthin and its analogues
    摘要:
    The synthesis of several analogues of (+/-)-semivioxanthin including five thiophene analogues, using directed metalation are reported. The strategy consisted of the synthesis of functionalized naphthalene or benzo[b]thiophene as building blocks followed by annelation of the pyrone. (C) 2003 Elsevier Science Ltd. All rights reserved.

    A short, simple and expedient synthesis of substituted benzo[b]thiophenes involving directed ortho lithiation-side-chain deprotonation-cyclisation-reduction is described. This method is a valuable improvement over earliersyntheses of the same class of compounds, both with respect to the number of steps and overall yields.

    日期:2003.6
    inexpensive synthesis of several diversely substituted benzo[b]thiophenes and one naphthothiophene is described. The method involves introduction of methylsulfanyl group ortho- to the amide function of readily available N,N-diethylamides of aryl carboxylic acid by directed metalation. Thioindoxyls, obtained in high yields through side-chain deprotonation and cyclisation in one pot, are reduced to benzo[b]thiophene
