Epoxides

Epoxides (oxiranes) have long been recognized as valuable building blocks which allow derivatization either by forming C-X bonds (through reactions with alcohols, ammonia, amines, phenolates, etc.) or by forming new C-C bonds (through reactions with cyanide, malonates, allyl silyl reagents, or metal-organic reagents). Sigma-Aldrich is the exclusive distributor of chiral epoxides manufactured by Rhodia Pharma Solutions, under license, using Jacobsen HKR technology. Additionally, we offer many epoxides from the ChiPros® portfolio.
