Cas no 43112-32-9 ((R)-6-Methyltetrahydro-2H-pyran-2-one)

(R)-6-Methyltetrahydro-2H-pyran-2-one is a chiral lactone compound characterized by its six-membered cyclic ester structure with a methyl substituent at the 6-position. This enantiomerically pure compound is of interest in organic synthesis and pharmaceutical applications due to its utility as a building block for complex molecules. Its rigid cyclic framework and stereocenter enable precise control over stereochemistry in reactions, making it valuable for asymmetric synthesis. The lactone functionality also allows for further derivatization, such as ring-opening or reduction, to yield diverse intermediates. High enantiomeric purity ensures reproducibility in research and industrial processes, while its stability under standard conditions facilitates handling and storage.
