A Safe, Simple, One-Pot Preparation of N-Derivatized β-Amino Alcohols and Oxazolidinones from Amino Acids

N-tert-Butoxycarbonyl, N-benzoyl, N-benzyloxycarbonyl, and oxazolidinone derivatives of β-amino alcohols have been prepared from amino acids in 72 to 90 % yields through lithium aluminum hydride reduction followed by in situ derivatization.
