Vladimir Prelog

Vladimir Prelog was a renowned organic chemist who made significant contributions to the field of stereochemistry, particularly in the area of asymmetric synthesis. He is best known for his work on the Cahn-Ingold-Prelog priority rules, which are used to assign stereochemical configurations to molecules. Prelog's research was heavily influenced by his collaborations with other prominent chemists, including Leopold Ružička and Albert Einstein. His work had a profound impact on the development of modern organic chemistry, and he is widely regarded as one of the most important chemists of the 20th century, alongside Marie Curie and Linus Pauling.

● Early Life and Education

Vladimir Prelog was born in Sarajevo, Bosnia and Herzegovina, to a family of Croatian descent. He spent his early years in Sarajevo and later moved to Zagreb, where he attended the University of Zagreb. Prelog's interest in chemistry was sparked by his father, a pharmacist who owned a pharmacy in Sarajevo. He went on to study chemistry at the University of Prague, where he earned his Ph.D. in 1929 under the supervision of Emil Votoček. During his time in Prague, Prelog was exposed to the works of prominent chemists, including Ernst Späth and Ladislav Šťastný, and developed a strong foundation in organic chemistry.

● Career

Prelog began his career as a research chemist at the Gaj factory in Zagreb, where he worked on the development of new dyes and pharmaceuticals. In 1935, he moved to Zürich, Switzerland, to work at the Swiss Federal Institute of Technology (ETH), where he collaborated with Leopold Ružička on the synthesis of steroids and other natural products. Prelog's work at ETH led to the development of new methods for the synthesis of complex molecules, including the use of Grignard reagents and Wittig reactions. He also worked closely with other prominent chemists, including Tadeusz Reichstein and Heinrich Otto Wieland, and made significant contributions to the field of biochemistry.

● Research and Contributions

Prelog's research focused on the synthesis and stereochemistry of complex molecules, including steroids, alkaloids, and sugars. He is best known for his work on the Cahn-Ingold-Prelog priority rules, which provide a systematic method for assigning stereochemical configurations to molecules. Prelog's work on the synthesis of adamantane and other polycyclic compounds also led to important advances in the field of organic chemistry. His research was influenced by the work of other prominent chemists, including Robert Burns Woodward and Derek Barton, and he made significant contributions to the development of modern stereochemistry. Prelog's work also had a profound impact on the field of pharmacology, particularly in the development of new drugs and therapies.

● Awards and Honors

Prelog received numerous awards and honors for his contributions to chemistry, including the Nobel Prize in Chemistry in 1975, which he shared with John Cornforth. He also received the Davy Medal from the Royal Society in 1962 and the Copley Medal in 1985. Prelog was elected a foreign member of the Royal Society in 1962 and a member of the National Academy of Sciences in 1960. He also received honorary degrees from several universities, including the University of Cambridge and the University of Oxford.

● Personal Life

Prelog was a private person who preferred to focus on his research rather than seeking to draw attention to himself. He was married to Kamila Vitek and had two children, Jan Prelog and Maja Prelog. Prelog was a talented pianist and enjoyed playing Chopin and other classical composers in his free time. He was also an avid hiker and enjoyed exploring the Swiss Alps and other mountain ranges. Despite his many accomplishments, Prelog remained humble and dedicated to his work, and he continued to make significant contributions to the field of chemistry until his death in 1998. Prelog's legacy continues to be celebrated by chemists around the world, including those at the University of Zürich and the ETH Zürich, where he spent much of his career.
