Nα-Fmoc-protected (2S, 3S)-β-methyltryptophan has been synthesized by asymmetric synthesis through the aid of an oxazolidinone auxiliary. Coupling of the mixed anhydride of Nin-Boc-protected indoleacrylic acid to the oxazolidinone auxiliary was achieved by lithium bromide and N, N-dimethylpyridine (DMAP). This reaction is milder and more convenient to run than the traditional conditions using butyl lithium.
