The title compound, C22H24INO4 is a chiral reagent developed and used for the synthesis of unnatural amino acids. It forms chains in its crystal structure, via weak N - H⋯O=C hydrogen bonds. The bulky iodo substituent lies gauche to the two substituents on the neighbouring C atom, about a C - C single bond, rather than gauche to one and trans to the other. This does not seem to be a consequence of any significant intermolecular interactions. The absolute configuration has been confirmed by this experiment and is as expected from the synthesis. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.
