The activation of the Nα--urcihanc protected (Fmoc-/Boc-/Z-/Bsmoc) α-amino acids employing l-[bis(dimethylamino)- methylene]-lH-l,2,3-triazolo-[4,5-6]pyridinium.0hexa-flurophosphate-3-oxide (HATU) followed by reduction of the in situ generated -OAt ester with NaBH 4 results in the corresponding ss-amino alcohols in good yields. This synthesis is the first demonstration of the application of the efficient coupling agent HATU for practical synthesis of ss-amino alcohols. The protocol is general for all common N-protecting groups including the highly base sensitive Bsmoc group. The protocol has also been successfully extended for the synthesis of peptide alcohols.
