A General and Scalable Synthesis of Polysubstituted Indoles

A consecutive 2-step synthesis of N-unprotected polysubstituted indoles bearing an electron-withdrawing group at the C-3 position from readily available nitroarenes is reported. The protocol is based on the [3,3]-sigmatropic rearrangement of N-oxyenamines generated by the DABCO-catalyzed reaction of N-arylhydroxylamines and conjugated terminal alkynes, and delivers indoles endowed with a wide array of substitution patterns and topologies.

Total synthesis of kopsine, fruticosine, and structurally related polycyclic caged Kopsia indole alkaloids

Kopsine, fruticosine and related caged and polycyclic Kopsia indole alkaloids have been attractive synthetic targets since 1983. Besides their promising bioactivities, the multiple continuous stereogenetic centers including two all-carbon quaternary stereocenters embedded in a rigid and caged polycyclic skeleton poses significant challenges in synthetic chemistry. Due to the extrodinary complex structures, tremendous efforts have been devoted to these synthetic targets. In this review, we discuss reported strategies for the total synthesis of kopsine, fruticosine and related Kopsia indole alkaloids with an emphasis on tactics to construct the polycyclic skeleton and methodologies to install the C7/C20 stereocenters.

Synthesis and Evaluation of Indole-Based Autoinducers on Quorum Sensing in Vibrio cholerae

Vibrio cholerae (V. cholerae) uses the autoinducer CAI-1 (cholera autoinducer 1) and several linked quorum sensing systems in order to efficiently sense its ever-changing environment and optimally coordinate population-wide gene expression. Indole has been reported as an important signal that is sensed by V. cholerae, and here, we report the synthesis and evaluation of a focused library of synthetic indole-CAI-1 derivatives as tools to probe quorum sensing (QS) in this human pathogen. Our results show interesting and diverging effects for several conjugates, as compared to CAI-1, on virulence factor production and biofilm formation.

Indole Pulse Signalling Regulates the Cytoplasmic pH of E-coli in a Memory-Like Manner

Bacterial cells are critically dependent upon pH regulation. Here we demonstrate that indole plays a critical role in the regulation of the cytoplasmic pH of Escherichia coli. Indole is an aromatic molecule with diverse signalling roles. Two modes of indole signalling have been described: persistent and pulse signalling. The latter is illustrated by the brief but intense elevation of intracellular indole during stationary phase entry. We show that under conditions permitting indole production, cells maintain their cytoplasmic pH at 7.2. In contrast, under conditions where no indole is produced, the cytoplasmic pH is near 7.8. We demonstrate that pH regulation results from pulse, rather than persistent, indole signalling. Furthermore, we illustrate that the relevant property of indole in this context is its ability to conduct protons across the cytoplasmic membrane. Additionally, we show that the effect of the indole pulse that occurs normally during stationary phase entry in rich medium remains as a memory to maintain the cytoplasmic pH until entry into the next stationary phase. The indole-mediated reduction in cytoplasmic pH may explain why indole provides E. coli with a degree of protection against stresses, including some bactericidal antibiotics.

Enantioselective C2-Alkylation of Indoles through a Redox-Relay Heck Reaction of 2-Indole Triflates

A palladium-catalyzed enantioselective redox-relay Heck reaction of 2-indole triflates and disubstituted alkenes is reported. This process combines readily available indole triflates with a variety of alkenes to afford a range of indole derivatives bearing a stereocenter adjacent to C2. Enantioselectivity is achieved through use of a simple pyridine-oxazoline ligand. Tuning the electronics of the indole, through judicious choice of N-protecting group, is required to ensure selective beta-hydride elimination away from the indole core. Utility of this method is highlighted in a modular formal synthesis of an S1P(1) agonist precursor developed by Merck.

The key role of protodeauration in the gold-catalyzed reaction of 1,3-diynes with pyrrole and indole to form complex heterocycles

Indole is a very common structural motif in alkaloids, and a number of them feature remarkable bioactive properties. Due to its relevant role in medicinal chemistry and the pharma-industry, many methods for indole synthesis have been developed, but only a few of them exploit the [4 + 2] approach. Recently a successful attempt at indole and carbazole formation via a formal gold mediated [4 + 2] addition of a diyne to pyrrole and indole rings has been reported by Ohno. A number of intriguing features observed in this reaction are however left to be resolved. We study here the mechanism of the Au-catalyzed reaction of 1,3-diynes with pyrrole and indole rings leading to substituted indoles and carbazoles, respectively. The reaction pathways are found to be significantly more complex than we had anticipated, for instance, in the case of the formation of carbazoles, one competitive route involves the formation of an unexpected spirane intermediate that evolves via a 1,2-alkenyl migration. Beyond this complexity, the current study also serves to highlight the importance of fundamental steps that are often disregarded as kinetically irrelevant, such as the protodeauration of reaction intermediates.
