CBr4 has been employed as a halogen bond donor catalyst for the selective activation of aldehyde, to achieve an efficient solvent- and metal-free C═C bond forming reaction in the presence of strong acid sensitive groups such as methoxy, cyanide, ester, and ketal for the synthesis of α,β-unsaturated ketones. This unique capability of CBr4 to act as a halogen bond donor has been explored and established
The present invention relates to the field of anti-invasive compounds and methods for predicting the anti-invasive activity of said compounds, as well as their use in the prevention and/or treatment of diseases associated with undesired cell invasion; in particular, this invention relates to the field of anti-invasive chalcone-like compounds.

The present invention relates to chalcone and chalcone derivatives and analogs which are useful as angiogenesis inhibitors. The present compounds, which are inexpensive to synthesize, exhibit unexpectedly good activity as angiogenesis inhibitors. The present invention also relates to the use of chalcone and its analogs as antitumor/anticancer agents and to treat a number of conditions or disease states in which angiogenesis is a factor, incluidng angiongenic skin diseases such as psoriasis, acne, rosacea, warts, eczema, hemangiomas, lymphangiogenesis, among numerous others, as well as chronic inflammatory disease such as arthritis.
