Abstract
The six-membered ring of the title ester [IUPAC name: tert-butyl 5-(hydroxymethyl)-2-(1-methylethyl)-3-oxopiperazine-1-carboxylate], C13H24N2O4, adopts a distorted half-chair configuration with C5 lying out of plane. Hydrogen bonds are formed between the OH group and the protecting carbonyl group, and between NH and the piperazine oxo group.
