Chiral Building Blocks in Asymmetric Synthesis: Synthesis …

WebFeb 5, 2011 · The stereogenic centers were installed by using Brown asymmetric allylation or chiral building blocks derived from d-glucose, respectively. The conjugate diene unit was introduced via an HWE reaction. WebHowever, acute control of the chirality of building blocks remains underexplored, 9,10 because of the complexity and subtlety of molecule design. In especial, chiral control of macrocycles, 11 which are of critical importance in supramolecular chemistry as host molecules or building blocks of supramolecular assemblies, are rarely reported. 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. open duckduckgo in microsoft edge
