Large-scale epidemiological studies have consistently shown that exposure to ambient particulate matter (PM) is responsible for a variety of adverse health effects. However, the specific physical and chemical properties of particles that are responsi

Using a meso-compound which is asymmetrically substituted with a chiral moiety as an intermediate, prostaglandins have been synthesized. Since the undesired enantiomer is readily recycled, this approach leads to a synthesis with high chiral efficienc
