Description
(R)-Butane-1,2-diol is a chiral diol featuring a defined stereochemistry at the C1 and C2 positions. This bench-stable compound serves as a valuable building block in asymmetric synthesis, where its stereoregular hydroxyl groups enable selective functionalization. The molecule integrates readily into complex frameworks requiring controlled spatial orientation.
Application
(R)-Butane-1,2-diol serves as a chiral synthon in asymmetric synthesis, enabling stereoselective transformations via its well-defined stereochemistry. Its bench-stable nature and compatibility with common protecting group strategies facilitate integration into complex molecule assembly. Functions as a key building block for pharmaceutical intermediates and natural product analogs, particularly in routes involving diol oxidation, epoxidation, or coupling reactions.
