Halichondrin B, Mount Everest in organic synthesis?
🌊 Dive into the fascinating world of Halichondrin B! 🧪
This polyether macrolide compound, found in the Okada sponge, boasts 32 chiral centers and a mind-blowing 4 billion+ stereoisomers! 🤯 It's like scaling Mount Everest in organic synthesis! ⛰️ Thanks to the genius of Yoshito Kishi and their team, at Harvard University, Halichondrin B's complete chemical synthesis was conquered in 1992. This breakthrough paved the way for eribulin, a simplified and optimized derivative, with exciting pharmaceutical potential! 💊
when I inevitably fail my mocks this week/next I don't think my teachers are going to take "was too mentally ill about a minecraft series" as an excuse you know,,
Researchers develop novel method to photosynthesize hydrogen peroxide using water and air
Researchers at the National University of Singapore (NUS) have developed a microporous covalent organic framework with dense donor–acceptor lattices and engineered linkages for the efficient and clean production of hydrogen peroxide (H2O2) through the photosynthesis process with water and air.
Traditional industrial production of H2O2 via the anthraquinone process using hydrogen and oxygen is highly energy-intensive. This approach employs toxic solvents and expensive noble-metal catalysts and generates substantial waste from side reactions.
In contrast, photocatalytic production of H2O2 from oxygen and water offers an energy-efficient, mild, and clean route. Most importantly, it addresses the common drawbacks of existing photocatalytic systems, such as low activity, heavy use of additional alcohol sacrificial donors, and the necessity for pure oxygen gas input.
Contents of the reaction flask are K2CO3, iodomethane, and a *slightly* conjugated imidazole (not nearly enough to explain a bright blue color) but this reaction in THF goes from all white powders and clear liquids to this blue to lovely pink then back to white. Can anyone explain why?
As part of this effort, the Molecular Design and Synthesis Group at the University of New South Wales has been designing tagging agents that will temporarily introduce highly fluorinated alkyl groups to molecules to aid in organic synthesis (for example, see figure 18.17).
