Advances in Heterocyclic Chemistry, Volume 128, is the definitive series in the field—one of great importance to organic chemists, polymer chemists and many biological scientists. Because biology and organic chemistry increasingly intersect, the associated nomenclature is being used more frequently in explanations. Written by established authorities in the field from around the world, this updated volume includes sections on Recent Advances in 1,2,4-Triazolo-[1,5-a]pyrimidine Chemistry, Fluorescent Heterocycles: Recent Trends and New Developments, and Reactions of 3-Pyrrolin-2-ones.
