International Summit on Chemical Reactions and Pharmaceutical Processes, Successfully Held
September 17-18, Tianjin, China – The International Summit on Chemical Reactions and Pharmaceutical Processes was held in Tianjin, China, organized by the Organic Reactions and Processes Sub-Committee of the Chinese Chemical Society and co-organized by Nankai University and Asymchem. The conference brought together more than 200 experts, scholars and researchers from universities, research institutes and pharmaceutical companies. Domestic and international experts in academia and business brought discussions with the theme of “New Technologies, New Methods, and Green Pharmaceutical Processes”on the latest scientific achievements in a variety of fields such as natural product synthesis, asymmetric synthesis, catalytic reactions, coupling reactions, and technological innovation. Renowned professors Stephen Leffler Buchwald and Jinquan Yu, Bin Zheng from Bristol-Myers Squibb and Bo Qu from Boehringer Ingelheim also completed an excellent online presentation and discussion. The conference aims to promote collaboration between academia and companies in the pharmaceutical industry. And, to promote the combination of industry and research for the industrialization of the latest research results, helping accelerate the development of innovative drugs in China.
The Photochemical Continuous Bromination of Benzyl Compound Successfully Piloted
Benzyl bromides are important intermediates for various APIs. A handful of substituted benzyl bromides are commercially available, which means that most of benzyl bromides require custom synthesis. Traditional processes usually employ hypervalent bromide as bromine sources and external radical initiators, most of these transformations require high temperature to achieve high conversion. In addition, these methods showed poor selectivity which are accompanied by by-products of multi-substituted brominates. The Asymchem photo- and electro-chemical team excite the bromides through photochemical method to generate bromine radicals, thereby enabling benzyl bromination at room temperature. And by controlling light intensity and reaction time, the generation of multi-substituted bromine was effectively avoid. The team achieved 100 kg amplification by combining photochemistry and flow chemistry. The related results have been patented and successfully applied to the synthesis of other drugs.
