In the title compounds, C22H20N2O4S, (I), and C22H19ClN2O4S, (II), the pyrrolidine rings have twist conformations on the spiro-spiro C-C bonds. In (I), the five-membered ring of the oxindole moiety has an envelope conformation with the spiro C atom as the flap, while in (II) this ring is flat (r.m.s. deviation = 0.042 Å). The mean planes of the pyrrolidine rings are inclined to the mean planes ...
A new metabolite of the plant growth substance indole-3-acetic acid has been extracted from Zea mays seedlings and characterized as the 7'-O-beta-D-glucopyranoside of 7-hydroxy-2-oxindole-3-acetic acid. This compound was the major product formed from [5-3H] 2-oxindole-3-acetic acid, incubated with intact plants or root and coleoptile sections. Identification was by gas chromatography-mass spect...
