Progress in Heterocyclic Chemistry (PHC), is an annual review series commissioned by the International Society of Heterocyclic Chemistry (ISHC). Heter Vol contain contain heter contain heter contain heter contain heter contain heter contain. Heterocyclic chemists. The highlight chapters in Volume 21 are all written in the literature. 'Biocatalytic approaches to chiral heterocycles' and 'Ring-expanded (' fat ') purines and their nucleoside / nucleotide analogues as broad-spectrum therapeutics'.
As with previous volumes in the series, Volume 21 will enable academic and industrial chemists, and advanced students, to keep abreast of developments in heterocyclic chemistry in a convenient way.
* Covers the heterocyclic literature published in 2008
* Includes specialized reviews
* Features contributions from leading researchers in their fields
