Gary H. Posner

From Wikipedia, the free encyclopedia

Gary H. Posner (June 2, 1943[1] – February 26, 2018[2]) was Scowe Professor of Chemistry at Johns Hopkins University in Baltimore, Maryland.[3] Posner is known for his pioneering research in organocopper chemistry, including his involvement in the development of the Corey–House–Posner–Whitesides reaction.

Career

[edit]

Posner was born in New York City[1] and completed his undergraduate studies at Brandeis University. He received his PhD from Harvard University in 1968 where his adviser was E. J. Corey. He did a post-doctoral fellowship at the University of California Berkeley. He was at Johns Hopkins University from 1969 to 2016, where he held the Scowe Professorship in Chemistry from 1989 onwards.

Research

[edit]

Posner was first known for his pioneering research in organocopper chemistry in which he developed novel methods for organic synthesis involving organocopper reagents.[4][5] He is the author of the textbook An Introduction to Synthesis Using Organocopper Reagents. Posner has also contributed numerous other developments in synthetic organic chemistry including asymmetric synthesis and multicomponent organic reactions.[6] Posner's recent research has been focused on applying organic synthesis to the preparation of novel medicinal agents including isothiocyanates with anticancer properties,[7] new vitamin D analogs for the treatment of psoriasis,[8][9] and new antimalarial peroxides.[10][11][12]

Awards

[edit]

In 1987, Posner was named Maryland Chemist of the Year and in 1994 he received the Distinguished Teaching Award at Johns Hopkins.[3] He was also a 2004 recipient of a Cope Senior Scholar Award from the American Chemical Society.[13]
