《Visible-Light-Induced Dehydrohalogenative Coupling for Intramolecular α-Alkenylation: A Way to Build Seven- and Eight-Membered Rings》 was written by Xu, Dawen; Li, Han; Pan, Guangxing; Huang, Pan; Oberkofler, Jens; Reich, Robert M.; Kuhn, Fritz E.; Guo, Hao. Quality Control of 4-Cyanobenzyl bromideThis research focused onvisible light dehydrohalogenative coupling photocycloaddition diene. The article conveys some information:

A visible-light-induced intramol. α-alkenylation has been developed via metal-free dehydrohalogenative C(sp2)-C(sp2) coupling reaction to afford seven- and eight-membered rings. Extensive mechanistic studies prove that this reaction proceeds through a [2+2]-photocycloaddition, elimination, and retro-[2+2]-photocycloaddition process, with cyclobutane and cyclobutene being involved as key intermediates. This transformation is broadly applicable and highly stereoselective, yielding exclusively cyclic (1Z,3Z)-1,3-diene via photochem. allowed disrotation. This protocol excavates new applications of [2 + 2]-photocycloadditions, which may find their way in future olefin-olefin coupling reactions and medium-sized ring synthesis. The experimental part of the paper was very detailed, including the reaction process of 4-Cyanobenzyl bromide(cas: 17201-43-3Quality Control of 4-Cyanobenzyl bromide)

And the article was published in Molecules in 2019. Application In Synthesis of 4-Cyanobenzyl bromide The author mentioned the following in the article:

Imatinib, an Abelson (ABL) tyrosine kinase inhibitor, is a lead mol.-targeted drug against chronic myelogenous leukemia (CML). To overcome its resistance and adverse effects, new inhibitors of ABL kinase are needed. Our previous study showed that the benzyl ester of gypsogenin (1c), a pentacyclic triterpene, has anti-ABL kinase and a subsequent anti-CML activity. To optimize its activities, benzyl esters of carefully selected triterpenes (PT1-PT6), from different classes comprising oleanane, ursane and lupane, and new substituted benzyl esters of gypsogenin (GP1-GP5) were synthesized. All of the synthesized compounds were purified and charachterized by different spectroscopic methods. Cytotoxicity of the parent triterpenes and the synthesized compounds against CML cell line K562 was examined; revealing three promising compounds PT5, GP2 and GP5 (IC50 5.46, 4.78 and 3.19 microM, resp.). These compounds were shown to inhibit extracellular signal-regulated kinase (ERK) downstream signaling, and induce apoptosis in K562 cells. Among them, PT5 was identified to have in vitro activity (IC50 = 1.44 microM) against ABL1 kinase, about sixfold of 1c, which was justified by mol. docking. The in vitro activities of GP2 and GP5 are less than PT5, hence they were supposed to possess other more mechanisms of cytotoxicity. In general, our design and derivatizations resulted in enhancing the activity against ABL1 kinase and CML cells. The experimental part of the paper was very detailed, including the reaction process of 4-Cyanobenzyl bromide(cas: 17201-43-3Application In Synthesis of 4-Cyanobenzyl bromide)
