Ivar Karl Ugi (Sep 9, 1930 in Saaremaa, Estonia - 29 September, 2005 Munich) was a German chemist who made major contributions to organic chemistry. He is known for the research on multicomponent reactions, yielding the Ugi reaction.



After he came to Germany from Estonia in 1941 he began his studies of chemistry in 1949 at the University of Tübingen until 1951. He became Dr. rer. nat. in 1954 at the Ludwig Maximilians University of Munich. He did his habilitation 1960 at the same university. After a short but very successful career in industry at Bayer from 1962 til 1968 he joined the University of Southern California at Los Angeles.

Since 1971 he worked at the Technical University of Munich, he was an emeritus from 1999 until his death in 2005.

Research and development

The one pot reaction of a ketone or aldehyde, an amine, an isocyanide and a carboxylic acid to form a bis-amide is generally known as Ugi reaction.
