The structures of benzyl nzyl-N-(p-toluene-sulfonyl)amino]-2-phenylace
tate, C29H27NO4S, (I), and -benzyl-N-(p-toluenesulfonyl)amino]-2-pheny
lacetic acid, C22H21NO4S, (II), have been determined. The geometries o
f both compounds are similar. The N atoms and the carboxylic C atoms a
re sp2 hybridized. The N-C(8)-C(9)-O(3) torsion angle in compound (I)
[-18.4 (5)-degrees] and the N-C(8)-C(15)-O(4) torsion angle in compoun
d (II) [9.6 (4)-degrees] characterize a synperiplanar conformation for
the N atom and the O atom of the C=O group in both compounds studied.
