title: Di-tert-butyl 2,2'-[(2-hydroxy-ethyl)aza-nedi-yl]diacetate.
abstract: In the title compound, C(14)H(27)NO(5), the hydr-oxy group and one of the acetate carbonyl O atoms are linked by an intra-molecular O-H⋯O hydrogen bond, forming an eight-membered ring. This inter-action gives rise to an asymmetric mol-ecular conformation.
