Facile Installation of 2-Reverse Prenyl Functionality into Indoles by a Tandem N-Alkylation-Aza-Cope Rearrangement Reaction and Its Application in Synthesis

An unprecedented tandem N-alkylation-ionic aza-Cope (or Claisen) rearrangement-hydrolysis reaction of readily available indolyl bromides with enamines is described. Due to the complicated nature of the two processes, an operationally simple N-alkylation and subsequent microwave-irradiated ionic aza-Cope rearrangement-hydrolysis process has been uncovered. The tandem reaction serves as a powerful approach to the preparation of synthetically and biologically important, but challenging, 2-reverse quaternary-centered prenylated indoles with high efficiency. Notably, unusual nonaromatic 3-methylene-2,3-dihydro-1H-indole architectures, instead of aromatic indoles, are produced. Furthermore, the aza-Cope rearrangement reaction proceeds highly regioselectively to give the quaternary-centered reverse prenyl functionality, which often produces a mixture of two regioisomers by reported methods. The synthetic value of the resulting nonaromatic 3-methylene-2,3-dihydro-1Hindole architectures has been demonstrated as versatile building blocks in the efficient synthesis of structurally diverse 2-reverse prenylated indoles, such as indolines, indolefused sultams and lactams, and the natural product bruceolline D.

Addition of Chloroprene Grignards to Aromatic Aldehydes: Synthesis of Homoallenyl Alcohols

A general procedure for the one-pot synthesis of racemic homoallenyl alcohols from the corresponding aldehyde and chloroprene-derived Grignards is described. Employing bis[2-dimethylaminoethyl]ether (BDMAEE) as an additive at low temperatures shifts the selectivity of the chloroprene Grignard addition to aldehydes such that it is almost exclusive toward allene formation. In a set of follow-up experiments, simple and more elaborate methods for further derivatization have been demonstrated, allowing quick access to more complex structures.

Design, synthesis, stereochemical determination, molecular docking study, in silico pre-ADMET prediction and anti-proliferative activities of indole-pyrimidine derivatives as Mcl-1 inhibitors

In this study, fourteen novel indole-pyrimidine hybrids were designed and synthesized. Their chemical structures were confirmed using different spectroscopic techniques (1H NMR, 13C NMR, IR and mass). Their (E) stereochemical configuration was determined theoretically (MM2 property) and experimentally using 2D NMR technique (NOESY experiment). The prepared compounds were subjected to preliminary biological studies as Mcl-1 inhibitors. Most of the compounds exhibited good abilities for targeting Mcl-1 protein, especially, 7d, 7e, 7i and 7k (Ki = 11.19–15.21 nM). These derivatives were further evaluated against Bcl-XL and Bcl-2 proteins. Some compounds were found to have dual Mcl-1/Bcl-XL such as 7i, or Bcl-XL/Bcl-2 inhibitory activity as 7d. The most potent derivatives as Mcl-1 inhibitors were chosen as representative examples for determination of in-vitro anti-proliferative activity against PC-3, K-562 and MDA-MB-231 cell lines. They possessed excellent to good anti-proliferative activities. All of the synthesized compounds were docked into Mcl-1 active site. Drug-likeness properties and in silico pre-ADMET characters were also predicted.

A Gold Carbene Manifold to Prepare Fused γ-Lactams by Oxidative Cyclisation of Ynamides

Gold-catalysed oxidative cyclisation reactions of ynamides offer great promise in γ-lactam synthesis but are limited by preferential over-oxidation to form α-keto imides. Evaluating the factors that might limit N-cyclisation pathways led to effective gold-catalysed conditions that allow access to different fused γ-lactams on changing the ynamide N-substituent and accommodate previously incompatible substitution patterns. New and efficient methods for the synthesis of functionalised 3-aryl indoles and cyclohepta[c]pyrrol-1-one derivatives are presented. These conditions illustrate the complementarity of gold catalysis to other metals.
