  Benzoyl 2-methyl indoles as selective PPARγ modulators

  摘要：

  Routine screening for human PPAR ligands yielded compounds 1 and 2, both of which were sub-micromolar hPPARgamma agonists. Synthetic modifications of these leads led to a series of potent substituted 3-benzyl-2-methyl indoles, a subset of which were noted to be selective PPARgamma modulators (SPPARgammaMs). SPPARgammaM 24 displayed robust anti-diabetic activity with an improved therapeutic window in comparison to a PPARgamma full agonist in a rodent efficacy model. (C) 2004 Elsevier Ltd.

  afford the corresponding 2‐alkylbenzoic acids in moderate to excellent yields. This C−H alkylation process is generally applicable to diversely substituted electron‐rich and electron‐deficient benzoic acids, along with α,β‐unsaturated olefins including unprotected acrylic acid. The widely available carboxylate directing group can be removed or utilized for further derivatization. Mechanistic investigations

  日期：2021.2.5

  Organo‐radical catalysts have recently attracted great interest, and the development of this field can be expected to broaden the applications of organocatalysis. Herein, the first example of a radical‐generating system is reported that does not require any photoirradiation, radical initiators, or preactivated substrates. The oxidative C−C‐bond cleavage of 2‐substituted cyclohexanones was achieved
