"for his pioneering application of statistical thermodynamics and spectroscopy to our understanding of the properties of organic and inorganic materials" lecturer and professor (19351964 and 19711984) and dean (19511960) of the College of Chemistry at UC Berkeley: Peter H. Raven: BS 1957: 2000 Kato, Ritsuki; This new approach includes two efficient continuous flow reductive aminations achieved via photoredox catalysis and a final batch acylation. Between 1968 and 1997, there were only a few reports of the use of small organic molecules as catalysts for asymmetric reactions (the HajosParrish reaction probably being the most famous), but these chemical studies were viewed more as unique chemical reactions than as integral parts of a larger, interconnected field. Chiral catalysts induce asymmetric reactions, often with high enantioselectivities.
