Both natural and synthetic brominated furanones are known to inhibit biofilm formation by bacteria, but their toxicity to mammalian cells is often not reported. Here, we designed and synthesized a new class of brominated furanones (BBFs) that contained a

, p. 6781 - 6787 (2017/12/07)
We report the first stereoselective synthesis of (2R,3aR,7aR)- and (2S,3aS,7aS)-octahydroindole-2-phosphonic acid 2 (OicP derivatives). The key points are the highly diastereoselective synthesis of cis-fused bicyclic (3aR,7aR)- and (3aS,7aS)-pyrrolidin-2-ones 4 through a dynamic kinetic resolution of racemic γ-keto acid (±)-5 with (R)- and (S)-phenylglycinol via Meyers' bicyclic lactams, and the highly diastereoselective addition of trimethyl phosphite to the N-acyliminium ions 3 obtained from 4.

Asymmetric olefin isomerization of butenolides via proton transfer catalysis by an organic molecule
Wu, Yongwei,Singh, Ravi P.,Deng, Li
supporting information; experimental part, p. 12458 - 12461 (2011/10/09)
An unprecedented enantioselective and general olefin isomerization was realized via biomimetic proton transfer catalysis with a new chiral organic catalyst. A broad range of mono- and disubstituted β,γ-unsaturated butenolides were transformed into the corresponding chiral α,β- unsaturated butenolides in high enantioselectivity and yield in the presence of as low as 0.5 mol % catalyst. Mechanistic studies have revealed the protonation as the rate-determining step.
Direct enantioselective bronsted acid catalyzed N-acyliminium cyclization cascades of tryptamines and ketoacids
Holloway, Chloe A.,Muratore, Michael E.,Storer, R. Lan,Dixon, Darren J.

A direct enantio- and diastereoselective N-acyliminium cyclization cascade through chiral phosphoric acid catalyzed condensation of tryptamines with γ- and δ-ketoacid derivatives to provide architecturally complex heterocycles has been developed. The reac
Synthesis of 2,6-dioxo-1,2,3,4,5,6-hexahydroindoles by acid-catalyzed cyclization of acetal-protected (2,4-dioxocyclohex-l-yl)acetamides and their transformation into 5,8,9,10-tetrahydro-6H-indolo[2,1-a]isoquinolin-9-ones

supporting information; experimental part, p. 1073 - 1079 (2009/12/05)
Acetal-protected (2,4-dioxocyclohex-1-yl)-acetic acids were prepared by allylation of dilithiated 1,3-cyclohexane-1,3-diones, protection of the carbon-yl groups and oxidation of the alkene moiety. Their reaction with amines afforded the corresponding amides which were transformed, by acid-catalyzed cyclization, into various 2,6-dioxo-1,2,3,4,5,6-hexahy-droindoles. The reaction of the latter with triflic acid resulted in the formation of novel 5,8,9,10-tetrahy-dro-6H-indolo[2,1-a]isoquinolin-9-ones.
