Indoxyl-based umpolung strategy for the synthesis of unsymmetrical 3,3′-biindoles

3,3′-Bisindoles are known to be important structural motifs found in bioactive natural products, pharmaceuticals, and functional materials. Herein, a novel indoxyl-based approach was established for the synthesis of unsymmetrical 3,3′-biindoles from indoles and indoxyls. This approach generated moderate to excellent yields of the desired products (24 examples, up to 98% yield). The present method features broad substrate scope, operational simplicity, high atom economy, and utilization of non-toxic and inexpensive molecular iodine as catalyst. The applicability of this method has been demonstrated by the facile gram-scale synthesis.

N-heterocyclic carbene-catalyzed enantioselective annulation of indolin-3-ones with bromoenals

N-Heterocyclic carbene-catalyzed reactions of indolin-3-ones with 2-bromoenals opened an asymmetric access to 3,4-dihydropyrano[3,2-b]indol-2(5 H)-ones in good yields and with good to excellent enantioselectivities. This protocol tolerates a broad substrate scope. In addition, a possible mechanism for the annulation reaction is presented.

Design, synthesis and pharmacological evaluation of conformationally restricted N-arylsulfonyl-3-aminoalkoxy indoles as a potential 5-HT6 receptor ligands

A series of novel conformationally restricted N1-arylsulfonyl-3-aminoalkoxy indoles were designed and synthesized as 5-HT6 receptor (5-HT6R) ligands. Many of the synthesized compounds have moderate in vitro-binding affinities at 5-HT6R. The lead compound 8b (% inhibition=97.2 at 1 μM) from this series has good pharmacokinetic profile in male Wister rats and is active in animal model of cognition like Morris water maze. The details of chemistry, SAR, pharmacokinetics and pharmacological data constitute the subject matter of this report.
