Controlling the stereochemical outcome for various synthetic routes using chiral auxiliaries enables the synthesis of many enantiomerically pure compounds in a time-efficient manner. By temporarily attaching these structures to an organic compound, the auxiliary can influence the stereoselectivity of future reactions. Once the stereoselective protection is no longer needed, the chiral auxiliary can be removed and recycled for future uses. Asymmetric synthesis plays a crucial role in the chemical production of certain therapeutic and natural product compounds in enantiomeric form. We offer a market-leading range of innovative ephedrine derivatives, oxazolidinone derivatives, and sulfur-based chiral auxiliaries to aptly suit your applications.
