catalyst-free chemoselective trimerization reaction of readily available isocyanides is described. This domino reaction provides facile access to a wide range of 2-(indol-2-yl)-quinolines and 2-(indol-2-yl)-pyridines in moderate to excellent yields. A “head to head” heterodimerization of two isocyanides is proposed as the key step of this reaction.
yielding steps by combining the Ugi or Passerini multicomponent reactions with two metal‐catalyzed cyclizations: an intramolecular Tsuji–Trost reaction of the isocyanide‐derived amide followed by a ring‐closing metathesis. Scaffold diversity may be explored by the appropriate choice of starting unsaturated isocyanides. The Tsuji–Trost cyclization proceeds with moderate to good diastereoselectivity, and the

The invention relates to the use of substituted oxotetrahydroquinolinylsulfonamides or salts thereof
where the radicals in the general formula (I) correspond to the definitions given in the description, for enhancing stress tolerance in plants to abiotic stress, and/or for increasing plant yield.
The present invention relates to non-steroidal progesterone receptor modulators of the general formula I,
the use of the progesterone receptor modulators for the manufacture of medicaments, and pharmaceutical compositions which comprise these compounds.
The compounds according to the invention are suitable for the therapy and prophylaxis of gynecological disorders such as endometriosis, leiomyomas of the uterus, dysfunctional bleeding and dysmenorrhoea, and for the therapy and prophylaxis of hormone-dependent tumours and for use for female fertility control and for hormone replacement therapy.
