  摘要：

  我们继续探索3,3-二烷基-5-芳基吲哚系列孕酮受体（PR）调节剂，以寻找用于女性保健的新药物：避孕，肌瘤，子宫内膜异位症和某些乳腺癌。先前，我们报道了该模板和相关模板的微妙结构变化在激动剂和拮抗剂特性之间产生了功能转换（Fensome等，Biorg。Med。Chem。Lett。2002，12，3487; 2003，13，1317）。我们在本文中报道了5-（2-氧代吲哚-5-基）-1 H-吡咯-2-腈类化合物中的新功能开关。我们发现3，3-二烷基取代基的大小对于控制功能响应很重要。因此，小的基团（二甲基）提供有效的PR拮抗剂，而较大的基团（螺环己基）是PR激动剂。

  concise new synthetic route to furo[2,3-b]indolines has been developed by taking advantage of the reactivity of N-alkenyloxyindole intermediates. These compounds spontaneously undergo [3,3]-sigmatropic rearrangement followed by cyclization to form hemiaminals as single diastereomers. Tin-promoted N-hydroxyindole formation followed by conjugate addition to activated alkynes provides simple and modular
