摘要
The title compounds （S）-methyl-2-（4-R-phenylsulfonamido）-3-（1H-indol-3- yl）propanoate （R = H （1）, Cl （2）） have been synthesized and their crystal structures also have been determined by X-ray single-crystal diffraction. Compound 1 （C18H18N2O4S） belongs to orthorhombic, space group P212121 with a = 9.6348（14）, b = 11.1517（17）, c = 16.412（3） A, V = 1763.4（5） A^3, Mr = 358.40, Z = 4, De = 1.350 g/cm^3,/t = 0.209 mm^-1, F（000） = 752, R = 0.0348 and wR = 0.0714. Compound 2 （CI8H17ClN2O4S） crystallizes in orthorhombic, space group P212121 with a = 9.3128（14）, b = 10.9655（16）, c = 17.783（3） A, V = 1815.9（5） A^3, Mr = 392.85, Z = 4, De = 1.437 g/cm^3, p = 0.352 mm^-1, F（000） = 816, R = 0.0389 and wR = 0.0845. The absolute structure Flack parameters X of compounds 1 and 2 are -0.03（8） and -0.06（7）, respectively. X-ray analysis reveals that the crystal structures of these two compounds both involve two intermolecular N-H…O hydrogen bond＇s.
