【Abstract】 The title compound,methyl-p-tolysulfonyl-glycine (TsGlyHMe) has been synthesized from the reaction ofp-tolysulfonyl-glycine with solvent molecule of methanol in the presence of rare earth ion.The structure has been determined by X-ray diffraction method.The crystal crystallize in triclinic system,space groupP 1-with C 10H 13NO 4S,Mr=243.27,cell parameters:a=0.60266(10)nm,b= 0.70297(12)nm,c=1.3948(2)nm,α=83.647(4)°,β=80.931(4)°,γ=84.388(3)°,V=0.57801(17)nm3,Z=2,D c=1.398g/cm3,R 1=0.0549,wR 2=0.1661.The molecule exists in the crytal in a form of "V" model.Two molecules are joined to give a dimer by classical hydrogen bond,and the connection of the dimers via the unclassical hydrogen bond provides a 2-D network.The improved methods for the syntheses of tolylsulfonyl chloride and N-p-tolysulfonyl amino acids have been described in this work.更多还原
