TiCl4/t-BuNH2-Promoted Hydroamination/Annulation of δ-Keto-acetylenes: Synthesis of Novel Pyrrolo[1,2-a]indol-2-carbaldehydes
摘要:
[GRAPHICS]An original TiCl4/t-BuNH2-mediated hydroamination/annulation domino reaction of delta-keto-acetylenes is described. The synthesis of pyrrolo[ 1,2-a] indole-2-carbaldehydes, starting from 2-carbonyl-1-propargyl-1H-indoles runs under mild reaction conditions. A conceivable mechanism is also discussed. TiCl4 has proved to be an effective multiactivity reagent: catalyst/Lewis acid/water scavenger. Some unpublished 2-carbonyl-1-propargyl- 1H-indoles are prepared by means of Suzuki- and Negishi-type reactions.

evaluation, and activity of a novel class of HIVproteaseinhibitors are described. The initial lead compounds 2 and 3 were designed by modeling replacement groups for the C-terminal Val-Val-OCH3 of a known hydroxyethylene inhibitor into the active site of the reported crystal structure of HIVprotease complexed with MVT-101. The lead compound 2 was found to be a modest inhibitor with a Ki = 1.67 microM

acyl group linked to the triple bond. By contrast with the previously reported gold-catalyzed reaction of β-(2-aminophenyl)-α,β-ynones, which resulted in the formation of dibenzo[1,5]diazocines through a sequential process triggered by an intermolecularhydroamination, a selective intramolecular anti-Michael hydroamination was observed in the present study by silver/copper catalysis.

asymmetric allylic substitution/isomerization process with central chirality transposition. This process takes advantage of the ambident reactivity of the 2-indole imine methide generated in situ from racemic tertiary indolylmethanols. The use of a suitable chiralphosphoricacid catalyst and an ortho-directing group allowed regioselective formation a C–C bond at the 3 position but enantiocontrolled construction

An organocatalytic enantioselective formal hydroarylation of 2-vinyl indoles for the preparation of enantioenriched 2,3′-bis(indolyl)methanes bearing an all-carbonquaternarystereocenter is described. This reaction features mild conditions, low catalyst loading, excellent efficiency and enantioselectivity. The obtained products showed promising anticancer activity.
