Description
(R)-4-tert-Butyl-2-oxazolidinone is a bench-stable chiral auxiliary featuring a sterically hindered tert-butyl group that enhances configurational stability. This oxazolidinone integrates readily into asymmetric synthesis, enabling high diastereoselective transformations in natural product and pharmaceutical development.
Application
(R)-4-tert-Butyl-2-oxazolidinone serves as a robust chiral auxiliary in asymmetric synthesis, enabling stereoselective enolate formation and subsequent C–C bond construction. Its bench-stable, crystalline nature facilitates straightforward handling and purification. The oxazolidinone core exhibits excellent functional group tolerance and reliably delivers high diastereoselectivity in alkylation and aldol reactions, making it a practical choice for iterative synthetic strategies in medicinal chemistry and natural product synthesis.
