(from preface)

The tenth volume of this serial publication comprises six chapters, four of which deal with the general chemistry of a specific group of heterocyclic compounds: pyridopyrimidines (W. J. Irwin and D. G. Wibberley), benzofuroxans (A. J. Boulton and P. B. Ghosh), isoindolee (J. D. White and M. E. Mann), and pyrylium salts (A. T. Balaban, W. Schroth, and G. Fischer). The remaining chapters are concerned with indole Grignard reagents (R. A. Heacock and S. Kasparek) and with cyclic hydroxamic acids (J. B. Bapat, D, St. C. Black, and R. C. Brown).The international flavor of the publication is preserved: our contributors come from six countries in three continents.
We thank the authors and publishers for their cooperation which has allowed production of this volume in less than one year.
