A carefully curated review of the scientific literature, Volume 112 of Organic Reactions commemorates the 50th anniversary of the Ugi reaction. It explores the practical and theoretical aspects of one of the most widely used reactions in organic chemistry, focusing on the main Ugi reaction as well as on its many variants. This volume is published in two parts, A and B. Launched in 1942, the Organic Reactions series today is a leading secondary- and tertiary-level source for organic chemists across the world.

A carefully curated review of the scientific literature, Volume 113 of Organic Reactions presents critical discussions of widely used organic reactions or particular steps of a reaction. The material is treated from a preparative viewpoint, with emphasis on limitations, interfering influences, effects of structure and the selection of experimental techniques. The work includes tables that contain all possible examples of the reaction under consideration. Detailed procedures illustrate the significant modifications of each method. Launched in 1942, the Organic Reactions series today is a leading secondary- and tertiary-level source for organic chemists across the world.
