“…NaN 3 as a deadly chemical is highly toxic and explosive, and it has been widely used in hospitals and agriculture for chemical preservative and pest control [38,39]. As a result of its efficient and selective scavenging capacity for 1 O 2 [40], the photooxidase-mimicking activity of Eosin Y is capable of being restricted by NaN 3 (Fig.…”

The reported fluorescent dye-based artificial light-responsive oxidase mimics are suffering from their low catalytic efficiency. To overcome the limitation, we report the photooxidase-mimicking activity of Eosin Y which can catalyze the oxidation of various chromogenic substrates such as 3,3′,5,5′-tetramethylbenzydine (TMB), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), 3,3′-diaminobenzidine (DAB), and o-phenylenediamine (OPD) by dissolved oxygen. The photooxidase-like activity of Eosin Y is highly efficient for TMB substrate, and its catalytic efficiency is higher than that of the reported fluorescein (130 fold) and 9-mesityl-10-methylacridinium ion (7.7-fold) mimetic photooxidase. Moreover, the photosensitized Eosin Y-TMB chromogenic system is utilized for colorimetric detection of highly toxic and explosive sodium azide (NaN 3 ) in a linear range from 5 to 500 μM with a limit of detection of 3.5 μM. The resulting colorimetric assay is selective and applied to determine NaN 3 in real lake water samples.

“…"Current sodium azide detection methods include chromatography [9][10][11] and electrochemical detection, [12][13][14] which involves complicated procedures and specialized instruments," said Professor Wang. He continued: "Fluorescence has emerg ed as a simple and rapid detection tool, and a few fluorescent probes for sodium azide have been reported.…”

described "in an elegant way how the consideration of biosynthetic aspects has led to the first total synthesis of dictazole B and its cyclobutane analogue. Their total synthesis of tubastrindole B has been achieved through a very original ring expansion starting from the dictazole pre cursor. In summary, a remarkable work clearly deserving the merits for best paper in 2015." Well done to both and their research team! And I suspect that the competition among the Thieme Chemistry authors will be even tougher this year to try to secure either the SYNLETT or the SYNTHESIS Best Paper Award 2016! The second contribution is a report on the intriguing and clever method developed by B. Wang and G.-J. Boons (USA) for the sensitive detection of inorganic azide, which is odorless, tasteless and remarkably poisonous! The third article is a story describing the radical intramolecular cyclization of hydrazones recently published by J.-R. Chen (P. R. of China) in Nat. Commun. The issue is completed by a Young Career Focus having F. Beuerle (Germany) as the protagonist.
