Atomfair tert-butyl (3R)-3-formylpyrrolidine-1-carboxylate (R)-1-Boc-3-pyrrolidinecarbaldehyde C10H17NO3 CAS 191347-94-1

Description

tert-butyl (3R)-3-formylpyrrolidine-1-carboxylate (CAS 191347-94-1) is a high-purity chiral building block widely used in pharmaceutical research and organic synthesis. This compound, with the molecular formula C₁₀H₁₇NO₃, features a stereocenter at the 3-position of the pyrrolidine ring, making it a valuable intermediate for asymmetric synthesis. The tert-butyloxycarbonyl (Boc) protecting group enhances stability and facilitates selective deprotection under mild acidic conditions. Its formyl group (–CHO) offers versatile reactivity for nucleophilic additions, reductive aminations, and other key transformations. Supplied as a clear to pale-yellow liquid or low-melting solid, this reagent is rigorously tested for purity (typically ≥95% by HPLC or GC) and stored under inert conditions to ensure optimal shelf life. Ideal for medicinal chemistry, peptidomimetics, and catalyst design.
