CBS Reduction
... History of CBS reduction and selectivity • In 1981 Itsuno et al reduced achiral ketones to chiral alcohols using alkoxy-amine-borane complexes in enantioselectivity and in high yield. • In 1987 E.J. Corey, with his co-workers, used oxazaborolidines to rapidlly reduce ketones in the presence of BH3- ...

Elias James Corey
Elias James ""E.J."" Corey (born July 12, 1928) is an American organic chemist. In 1990, he won the Nobel Prize in Chemistry ""for his development of the theory and methodology of organic synthesis"", specifically retrosynthetic analysis. Regarded by many as one of the greatest living chemists, he has developed numerous synthetic reagents, methodologies and total syntheses and has advanced the science of organic synthesis considerably.
