Abstract
The present review deals with recently reported novel natural flavones and flavonols (mid-1999 to early 2004), along with various biological and pharmacological activities as exhibited by these important groups of flavonoids. The present resumé lists 252 new naturally occurring flavones and flavonols reported during the period. Natural distribution by plant family of the flavonoids is considered; a variety of plant species belonging to fifty-two different plant families is mentioned as their natural sources. Therapeutic efficacies of these constituents are also cited. The review covers 231 references.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
