No2 Detection

A new fluorescent chemodosimeter for detecting NO2 has been synthesized. The sensing mechanism is based on the regeneration of the carbonyl group induced by the target molecule. This reaction gives rise to both colorimetric and fluorescent changes. A LOD of 0.1 ppm has been determined.

Fluorescent Chemodosimeter

A smart ratiometric red fluorescent chemodosimeter (AH) has been explored for specific detection of F− with a lowest detection limit of 3.45 × 10−10 M. The sensing mechanism was worked out as fluoride-triggered deprotonation of imidazole accompanied by deprotection of the nosylate group.

The One

<div><div><div><div><p>A very concise total synthesis of (+)-brefeldin C starting from 2-furanylcyclopentene is described. This approach is based on an unprecedented enantioselective radical hydroalkynylation process to introduce the two cyclopentane stereocenters in a single step. The use of a furan substituent allows to achieve a high trans diastereoselectivity during the radical process and it contains the four carbon atoms C1–C4 of the natural product in an oxidation state closely related to the one of the target molecule. The eight-step synthesis require six product purifications and it provides (+)-brefeldin C in 18% overall yield.</p></div></div></div></div>
