title: Crystal structure of (2S)-3-methyl-2-[(naphthalen-1-ylsulfon-yl)amino]-butanoic acid.
abstract: The title compound, C15H17NO4S, was synthesized from l-valine and naphthalene-1-sulfonyl chloride. The hydrogen-bonded carb-oxy-lic acid groups form a catemer C(4) motif extending along [100]. The catemer structure is reinforced by a rather long N-H⋯O hydrogen bond, between the sulfamide N-H group and a carb-oxy-lic acid O atom [H⋯O = 2.52 (2) Å], and a C-H⋯O hydrogen bond.
