Bis{[1-(tert-butoxycarbonyl)pyrrolidin-2-yl]methyl} carbonate

L.-H. Jing

Abstract: The asymmetric unit of the title compound, C₂₁H₃₆N₂O₇, consists of two independent half-molecules, the other halves being generated by twofold rotational axes. The two independent half-molecules are related by a pseudo-inversion center. In one, the pyrrolidine ring adopts a twist conformation whereas in the other it is in an envelope conformation. The crystal packing is stabilized by C-HO hydrogen bonds.
