BOIMPYs: Rapid Access to a Family of Red-Emissive Fluorophores and NIR Dyes was written by Patalag, Lukas J.;Jones, Peter G.;Werz, Daniel B.. And the article was included in Angewandte Chemie, International Edition in 2016.Product Details of 15186-48-8 This article mentions the following:

A fundamental, highly fluorescent, and easily accessible scaffold derived from the BODIPY core is reported. The use of benzimidazole as a bridging ligand at the meso position enables the binding of two BF₂ units to provide sufficient rigidity and enhanced electron-withdrawing strength. Absorption and emission events thus take place in the red (λ≈600 nm); the fluorescence quantum yields can reach unity (0.96) and show little dependence on solvent polarity. The synthetic route was shortened to two steps starting from com. available precursors while the preparation is modular and tolerates various pyrrole and benzimidazole moieties. Fluoride replacement by propynyl groups, various halogenations, as well as Knoevenagel-type condensations were applied to extend the versatility of these new photostable fluorophores, which we termed BOIMPYs. In the experiment, the researchers used many compounds, for example, (R)-2,2-Dimethyl-1,3-dioxolane-4-carbaldehyde (cas: 15186-48-8Product Details of 15186-48-8).

Parallel synthesis of a library of bidentate protein tyrosine phosphatase inhibitors based on the α-ketoacid motif was written by Chen, Yen Ting;Seto, Christopher T.. And the article was included in Bioorganic & Medicinal Chemistry in 2004.Application In Synthesis of 1-(6-Aminobenzo[d][1,3]dioxol-5-yl)ethanone This article mentions the following:

Protein tyrosine phosphatases (PTPases) regulate intracellular signal transduction pathways by controlling the level of tyrosine phosphorylation in cells. These enzymes play an important role in a variety of diseases including type II diabetes and infection by the bacterium Yersinia pestis, which is the causative agent of bubonic plague. This report describes the synthesis, using parallel solution-phase methods, of a library of 104 potential inhibitors of PTPases. The library members are based on the bis(aryl α-ketocarboxylic acid) motif that incorporates a carboxylic acid on the central benzene linker. This carboxylic acid was coupled with a variety of different aromatic amines through an amide linkage. The aromatic component of the resulting amides is designed to make contacts with residues that surround the active site of the PTPase. The library was screened against the Yersinia PTPase and PTP1B. Based upon the screening results, four members of the library were selected for further study. These four compounds were evaluated against the Yersinia PTPase, PTP1B, TCPTP, CD45, and LAR. Compound 14 has an IC₅₀ value of 590 nM against PTP1B and is a reversible competitive inhibitor. This affinity represents a greater than 120-fold increase in potency over compound 2, the parent structure upon which the library was based. A second inhibitor, compound 12, has an IC₅₀ value of 240 nM against the Yersinia PTPase. In general, the selectivity of the inhibitors for PTP1B was good compared to LAR, but modest when compared to TCPTP and CD45.

And the article was included in Journal of Organic Chemistry in 2016.Synthetic Route of C6H12O2 This article mentions the following:

A revised structure for the Lycopodium alkaloid huperzine N,is proposed and confirmed by synthesis. The key synthetic steps involve an epimerization of a cis-5-oxodecahydroquinoline to the corresponding trans isomer and a coupling, followed by a diastereoselective hydrogenation using Wilkinson’s catalyst to incorporate the pyridylmethyl moiety. This route allowed the alkaloid serralongamine A, I, to be synthesized for the first time, and two addnl. steps led to the revised structure of huperzine N, II, both products bearing an unusual decahydroquinoline stereostructure.
