The preparation, characterization, and molecular and crystal structures of the title compound [IUPAC name: 2-nitrophenyl 2-methyl-2-(para-toluenesulfonylamino)propanoate], C(17)H(18)N(2)O(6)S, are reported. The phenyl group is almost perpendicular to the plane of the adjacent ester moiety. One O atom of the nitro group is wedged between the two ester O atoms. The implications of this peculiar conformation
标题化合物[IUPAC名称:2-硝基苯基2-甲基-2-(对甲苯磺酰基氨基)丙酸酯],C(17)H(18)N(2)O(6)的制备,表征以及分子和晶体结构)S。苯基几乎垂直于相邻酯部分的平面。硝基的一个O原子被楔在两个酯O原子之间。讨论了这种特殊构象对肽合成中邻硝基苯基酯化学的影响。
