Abstract
The dipeptide, N-(t-butoxycarbonyl)-L-alanyl-S-benzyl-L-cysteine methyl ester (Boc–Ala–Cys(Bzl)–OMe) has been crystallized in orthorhomic space group P212121 with cell dimensions of a = 9.565(1), b = 43.282(1), and c = 5.096(1) A. The structure was determined by direct methods and refined to an R-factor of 0.049. The molecules are packed in a parallel-pleated sheet arrangement and stabilized by N–H···O hydrogen bonds.
