Dear Colleagues,

It is a great honour and pleasure for me to invite you cordially to participate in the XXIV^th European Colloquium on Heterocyclic Chemistry, which will be held on August 23 – 27, 2010, at the Vienna University of Technology. This series of meetings has been initiated in 1974 in the French speaking areas of Western Europe and since then developed to a true European event organized every two years. The XXIV^th ECHC covers all aspects of heterocyclic chemistry with special focus on novel methods in heterocyclic synthesis and the application of heterocycles in medicinal chemistry, agrochemistry, sustainable chemistry, and materials.

Ideally located in the center of Europe, Vienna has a long-standing tradition as a major conference site since the "Congress of Vienna" in 1815. Its unique atmosphere will provide inspiration for a fruitful scientific meeting, and the participants will have ample time to enjoy a wealth of culture and historical places in and around Austria's capital city.
