Syntheses of Haptens Related to the Benzenoid and Indole Portions of Sporidesmin A; 13C N.M.R. Spectra of Indole Derivatives

Abstract
The syntheses of 2-amino-5-chloro-3,4-dimethoxybenzyl alcohol (2) and 5-chloro-6,7-dimethoxy-N- methyl-1H-indol-3-yloxoacetic acid (22), potential haptens related to the benzenoid and indole portions of the mycotoxin sporidesmin, are described. 13C N.M.R. assignments for the latter and ten related indole compounds are given.
