Cas no 21461-86-9 (2-Furancarboxylic acid,tetrahydro-2-methyl-5-oxo-, (2R)-)

2-Furancarboxylic acid, tetrahydro-2-methyl-5-oxo-, (2R)-, is a chiral furan derivative with significant utility in organic synthesis and pharmaceutical applications. Its stereospecific (2R) configuration makes it a valuable intermediate for asymmetric synthesis, particularly in the production of bioactive compounds. The tetrahydrofuran ring structure enhances stability while retaining reactivity, allowing for selective functionalization. The presence of both carboxylic acid and keto groups provides versatile reactivity for further derivatization, enabling its use in constructing complex molecular frameworks. This compound is particularly advantageous in fine chemical and medicinal chemistry research due to its well-defined stereochemistry and compatibility with a range of synthetic transformations.
