Abstract
Abstract The X-ray structure of the amino acid N-(tert- butoxycarbonyl)- l -alanine (B- l -ALA) has been determined and its IR spectrum interpreted. The molecules are held together by intermolecular OH···O hydrogen bonds between the carboxyl groups which are in a cyclic arrangement. Weaker hydrogen bonds are formed between the NH and carbonyl urethane groups. The IR spectrum of B- l -ALA differs markedly from that of N -( tert -butoxycarbonyl)glycine. The results are discussed as a function of the hydrogen bonding pattern of the two molecules and the higher asymmetry of the crystal packing in the glycine derivative.
