Synthesis and absolute configuration of (+) α-hydroxymethyltyrosine by X-ray analysis of its N-benzoyl derivative
摘要:
Alpha-Hydroxymethyltyrosine has been synthesized by a route involving alpha-hydroxymethylation. Dextrorotatory N-benzoyl-alpha-hydroxymethyltyrosine 4 crystallizes in space group P2(1)2(1)2(1) with cell parameters: a = 13.2266(9), b = 16.1099(9), c = 7.4475(5) angstrom, V = 15.86.9(2) angstrom-3, Z = 4. The structure was solved by direct methods and refined to R = 0.047 and R(w) = 0.066 with 1549 independent and 956 hklBAR reflections. The absolute configuration of 1 was determined as R by the application of Hamilton test and by the estimation of the Bijvoet coefficient B. Just as in N-benzoyl-alpha-methylcysteine (Wieczorek et al., 1989), the alpha-amino acid residue adopts the C5 ring conformation similar to the fully extended form. The two side chains also adopt an extended conformation around the C-alpha atom.
