Simple and efficient synthesis of chiral amino alcohols with an amino acid-based skeleton

Sodium bis(2-methoxyethoxy)aluminum hydride, NaAlH₂(OCH₂CH₂OCH₃)₂, commercially known as Vitride® or Red-Al®, enables rapid synthesis of pure optically active N-protected amino alcohols and peptide alcohols in very high yields. The method is very simple and attractive, as it does not require an additional step of N-protected amino acid derivatization and proceeds without the loss of enantiomeric homogeneity.
