The 16 accounts in Volume 7 are all written by leading researchers in their field and these accounts constitute a systematic survey of the important original material reported in the literature on heterocyclic chemistry in 1994. Chapter 1 surveys useful synthetic routes to "Polyfunctional Pyrroles and Pyrazoles" starting from conjugated azoalkenes. This review is based on the researches of O.A. Attanasi and his school in Urbino (Italy). The second review is unconventional, comprising a compilation of the "Application of Diels-Alder Cycloaddition Chemistry for Heterocyclic Synthesis". Written by the president of the International Society of Heterocyclic Chemistry, A. Padwa, it is in an unusual format, with a pertinent list of references dating back forty years in some cases. The remaining chapters deal with advances in the heterocyclic field, arranged in ascending order or ring size. As with previous volumes in the series, Volume 7 will enable academics and industrial chemists, and advanced students to keep abreast of developments in heterocyclic chemistry in an effortless way.

Progress in Heterocyclic Chemistry, Volume 2, reports on important original material abstracted from the 1989 literature of heterocyclic chemistry. The chapters are organized according to ring size and the type of heteroatom contained. The text is supported by clear diagrams, references and a subject index.

Progress in Heterocyclic Chemistry Volume 5 deals critically with original material selected essentially from the 1992 heterocyclic literature. Chapters 1 and 2 are given over to reviews: in the first, SO2 extrusion from five-membered rings is discussed by R.A. Aitken and colleagues, which completes last year''s review on this topic. The second review presents a review of 2-acylamino-3-dimethylaminopropenoates in heterocyclic synthesis. The chapters are arranged according to ring sizes as in the previous volumes and are supported by references, numerous diagrams and a subject index.

Progress in Heterocyclic Chemistry (PHC) Volume 6 reviews critically the heterocyclic literature essentially published in 1993. The first two chapters are given over to reviews. In Chapter 1 the fascinating subject of the "Halogen Dance" is comprehesively surveyed by J. Frohlich of the Technical University of Vienna. The author also discusses some of his unpublished results on the topic. The second review is of an entirely new format for PHC. The President of ISHC A. Padwa describes the application of selected "Heterocycles as Vehicles for Synthesis". The remaining chapters describe advances in the heterocyclic field arranged, as in previous volumes, according to ring-size. Numerous diagrams and a brief index are also included.
