Abstract
Phytohormones describe substances of plant origin with a hormonal activity. Epidemiological studies have shown a high health care potential for phytoestrogens. They are plant secondary metabolites with structural analogies to estradiol and with an influence on the estrogenic hormonal pathways. The main chemical classes are isoflavones, lignans, coumestans, prenylflavonoids and stilbene derivatives and occur in food and many health products. Soy and soy isoflavones represent an important source of phytoestrogens. Some human natural estrogens and androgens, or analogues, also occur in plants. Other hormones, such as melatonin, have also been found in plants.

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
