The relative configuration of the title compound, C 18 H 27 NO 4 , was determined as being R,S,S,S . There are three crystallographically independent molecules in the asymmetric unit, which show only slight conformational differences. Molecules in the crystal structure are connected by hydrogen bonds in ribbons along the a axis.
