AIDS is one of the most threatening diseases spread across the planet, affecting about 35 million people worldwide. To improve the quality of life of those affected by HIV, a number of antivirals were developed, such as Darunavir. This molecule has a complex bicyclic core, the synthesis of which is well documented in the literature.
State of the art: An approach described by Ghosh and his co-workers includes an ozonolysis step, which is performed under batch conditions resulting in the desired ketone with 98% yield after 3 hours.[6,7] However, handling the gaseous ozone and working at a very low temperature (78°C) is inconvenient. Adapting the synthesis to a continuous flow system
provides a safe and rapid alternative solution by using in-situ generated ozone, a closed system, and higher temperatures. In this application note, we demonstrate that continuous flow ozonolysis can easily be carried out utilizing the IceCube™ Flow Reactor, developed by ThalesNano, in a safe and efficient way.
