Organocatalytic Upgrading of Biomass Derived Building Blocks
European Journal of Organic Chemistry, Volume 26, Issue 22, June 6, 2023., 2023 The depletion of finite primary fossil fuels makes necessary a progressive transition from finite primary fossil sources to alternative renewable raw materials to produce high value chemicals important for our everyday life. Greener processes must be designed to face the current challenge of climate change.
