Description of Advances in Heterocyclic Chemistry Volume 57


Pyrans, thiopyrans, and seleno pyrans are comprehensively reviewed by Kuthan in the first unified treatment of this subject. The triazolopyridines were last reviewed in 196 1: the chemistry of these five heterocyclic systems is covered by Jones and Sliskovic.

Meisenheimer complexes from heteroaromatic compounds have been intensively investigated in the last 20 years, and the field has now been summarized by Illuminati and Stengel of the Rome group, who have contributed much to this area.

Advances in Heterocyclic Chemistry Volume 34 of this series contains a survey of 2H- and 3H-pyrroles, nonaromatic isomers of the common IH-pyrroles. The present volume includes two chapters on 3H- and 4H-pyrazoles, the nonaromatic isomers of “normal” 1H-pyrazoles, by Sammes and the series editor.
