(S)-(−)-1-Octyn-3-ol
(S)-(−)-1-Octyn-3-ol (CAS: 32556-71-1), with the molecular formula CH3(CH2)4CH(OH)C≡CH and a molecular weight of 126.20 g/mol, is a chiral secondary alcohol and an organic building block. It is particularly valuable as a key intermediate in the synthesis of prostaglandins and other complex organic molecules. Its specific stereochemistry makes it a useful component in asymmetric synthesis pathways.
Prostaglandin Synthesis
Serves as a crucial chiral building block for the stereoselective synthesis of prostaglandins, a class of lipid compounds with diverse hormone-like effects in mammals. Its defined stereochemistry is essential for producing pharmacologically active prostaglandin analogues.
Organic Synthesis Intermediate
Utilised as a versatile intermediate in the construction of complex organic molecules. The presence of both a hydroxyl group and a terminal alkyne allows for a variety of chemical transformations.
Asymmetric Synthesis
A valuable chiral synthon for introducing specific stereocentres in organic synthesis. Its optical purity enables its use in reactions where precise control over stereochemistry is required.
