Rac-Methyl 4-azido-3-hydr-oxy-3-(2-nitro-phen-yl)butanoate.

ABSTRACT: In the title compound, C(11)H(12)N(4)O(5), the mean plane through the nitro substituent on the benzene ring is inclined to the benzene mean plane by 85.8?(2)°, which avoids steric inter-actions with the ortho substituents. The hydr-oxy group is involved in bifurcated hydrogen bonds. The first is an intra-molecular O-H?O hydrogen bond, involving the ester carbonyl O atom, which gives rise to the formation of a boat-like hydrogen-bonded chelate ring. The second is an inter-molecular O-H?N hydrogen bond involving the first N atom of the azide group of a symmetry-related mol-ecule. In the crystal structure this leads to the formation of a polmer chain extending in the c-axis direction.
