Description

Application

Employed in the efficient reduction of N-Boc amino acid secondary amides leading to chiral diamines.

General description

Red-Al® sodium bis(2-methoxyethoxy)aluminum hydride [NaAlH2(OCH2CH2OCH3)2] is used as a versatile reducing agent in organic synthesis. It is used to reduce:
  • Aldehydes, ketones, esters, and anhydrides to primary alcohols.
  • Ketoximes and aldoximes to primary amines.
  • Cyclic compounds such as lactones and epoxides to diols.


It is also used as a catalyst in the ring-opening polymerization reactions.
