Mechanochemical Deracemization: A Sustainable Approach to Enantiopurity.

We introduce mechanochemical deracemization (MCDR) as a novel strategy for obtaining enantiopure compounds. This study demonstrates the successful transposition of six archetypical deracemization reactions from a solvent-based to a solvent-minimized ball milling environment. The scope includes a ketone, isoindolinones, imines, an ester, and an inorganic compound, all of which deracemized successfully.

[Bacteriology of maxillary sinusitis among members of the 11th parachutist unit].

When sinusoscopic examinations of chronic maxillary are made, bacteriological samples are the most often carried out. We report results of thirty one cases among young soldiers 19 to 23 years old. Our bacteriological results are similar to those reported in literature.
