Product Name:(S)-(-)-4-isopropyl-5,5-dimethyl-2-oxazolidinone
English Name:(S)-(-)-4-isopropyl-5,5-dimethyl-2-oxazolidinone
CAS No.:168297-86-7
Aliases:(S)-4-isopropyl-5,5-dimethyl-1,3-oxazolidin-2-one, (S)-5,5-dimethyl-4-isopropyl-2-oxazolidinone, (S)-(-)-4-propan-2-yl-5,5-dimethyl-1,3-oxazolidin-2-one
Molecular Formula:C8H15NO2
Physical Properties:Colorless to light yellow transparent liquid; molecular weight 157.21. Boiling point approximately 250°C; relative density approximately 0.97 g/cm³; flash point approximately 120°C. Soluble in ethyl acetate, ethanol and other organic solvents; slightly soluble in water. Specific rotation [α]D20 = −20° (c=1, CHCl3).
Uses:This compound features an Evans chiral auxiliary-type structure and can serve as a chiral template in asymmetric alkylation, Aldol condensation and other reactions, providing good stereoselectivity. It is widely used to construct chiral frameworks such as chiral amino acids and β-hydroxy acids, and is also an important starting material for preparing chiral catalysts and pharmaceutical intermediates.
