An efficient one-pot reaction of indoles, nitroacetate, and paraformaldehyde for the synthesis of tryptophan derivatives

An efficient method for the synthesis of tryptophan analogues has been developed via one-pot reaction of commercial available indoles, ethyl nitroacetate, and paraformaldehyde in the presence of molecular sieves. The reaction provided tryptophan nitro-precursors in moderate to good yields, which were further converted to alpha-hydroxymethylated tryptophan derivatives catalyzed by DABCO in high yields.

Oxidation of Benzylic and Allylic Alcohols with Cobalt(III) Acetate in Acetic Acid in the Presence and Absence of Sodium Bromide

Benzyl alcohol and its o-, m-, and p-substituted derivatives afforded fairly good yields of the corresponding benzaldehydes through a reaction with a Co(III)-NaBr system.With allylic alcohols, this system failed in a selective formation of unsaturated carbonyl compounds.In the latter cases, the products were effectively obtained by using a higher concentration of cobalt(III)acetate in the absence of NaBr.

Tryptamine Synthesis by Iron Porphyrin Catalyzed C?H Functionalization of Indoles with Diazoacetonitrile

The functionalization of C?H bonds with non-precious metal catalysts is an important research area for the development of efficient and sustainable processes. Herein, we describe the development of iron porphyrin catalyzed reactions of diazoacetonitrile with N-heterocycles yielding important precursors of tryptamines, along with experimental mechanistic studies and proof-of-concept studies of an enzymatic process with YfeX enzyme. By using readily available FeTPPCl, we achieved the highly efficient C?H functionalization of indole and indazole heterocycles. These transformations feature mild reaction conditions, excellent yields with broad functional group tolerance, can be conducted on gram scale, and thus provide a unique streamlined access to tryptamines.

Resonant Two-Photon Ionization Spectroscopic Analysis of Indole and Catechol Derivatives Using Pulsed Laser Desorption with Entrainment into Supersonic Jet Expansions

Pulsed laser desorption is used as a means of volatilizing thermally labile indole and catechol derivatives for entrainment into a supersonic jet expansion.The jet expansion provides ultracold molecules whose sharp spectral features are probed by resonant two-photon ionization (R2PI) spectroscopy in a time-of-flight mass spectrometer.Despite the structural similarity between many of the compounds studied herein, R2PI electronic spectrometry is shown to be a sensitive probe of small structural changes in these molecules and thus as a means of uniquely identifying each of these species.Target mixtures of various indole based compounds are studied under different conditions in order to establish the limitations to the selectivity of this technique.In addition, the limits of sensitivity are in the 10 pg range for these compounds and an optical spectrum can be obtained with as little as 300 ng of sample.

Unraveling the Hydrolysis of Merocyanine-Based Probes in Biological Assay

Merocyanine dyes, owing to their unique photochemical properties, are widely used to fabricate probes for the detection of biologically active small molecules and bioimaging. In this paper, merocyanine-based probes were proved of undergoing unwanted hydrolysis. To explore the strategies toward avoiding the hydrolysis, the detailed hydrolysis mechanism was first investigated, which was also confirmed by density functional theory (DFT) calculation. Then a series of merocyanine dyes were rationally designed. Influences of molecular structures of the probes, the analytical media such as pH and components of the solution on the hydrolysis were systematically studied. The experimental results suggest that merocyanine based probes with low electron density are more likely to suffer the hydrolysis, which could be exacerbated by the well-accepted strategy for constructing type-II probes. It is worth noting that chemical surroundings could also exert distinctive influence on the hydrolysis. The hydrolysis could be obviously aggravated when fetal calf serum or DMSO was deployed. Our findings will definitely provide an effective and reliable approach for guiding the rational design of highly robust merocyanine-based probes and the optimization of the analytical media, which is helpful in terms of avoiding the hydrolysis of the probes and hydrolysis caused analytical errors.
