WebJul 12, 2024 · Chiral 4,4–dimethyl tetrahydrofurans were synthesized using a chiral pool approach starting from both pantolactones. The synthesized building blocks are substituted with azide, amine, or alcohol groups making them interesting for applications in medicinal chemistry. WebIn the quest for new catalysts that can deliver single enantiomer pharmaceuticals and agricultural chemicals, chemists have extensively mined the “chiral pool”, with little in the way of inexpensive, readily available building blocks now remaining. It is found that Werner complexes based upon the D3 symmetric chiral trication [Co(en)3]3+ (en = 1,2 …
