Descripción

Descripción general

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.

SBAH is a reducing agent used to reduce functional groups like carbonyls, amides, epoxides, esters, and carboxylic acids.

Aplicación

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

Red-Al^® sodium bis(2-methoxyethoxy)aluminum hydride can be used as:       

• A tosyl deprotecting agent.       
• A catalyst for crosslinking of polyvinylsilanes (PVS) by Si-Si dehydrocoupling reaction in the presence of group 4 metallocene complexes.       
• A reducing reagent for the synthesis of optically active N-protected amino alcohols and peptide alcohols.
