title: Monoclinic modification of N-[(1,1-dimethyl-ethoxy)carbon-yl]-3-[(R)-prop-2-en-1-ylsulfin-yl]-(R)-alanine ethyl ester at 200 (1) K.
abstract: In the monoclinic polymorph of the title compound, C(13)H(23)NO(5)S, inter-molecular N-H⋯O hydrogen bonds link mol-ecules into one-dimensional chains along [100]. The atoms of the terminal propenyl group are disordered over two sets of sites with refined occupancies of 0.69 (2) and 0.31 (2).
