BUTYL-META-CYCLOHEPTYLPRODIGININE - A REVISION OF THE STRUCTURE OF THE FORMER ORTHO-ISOMER

A red pigment produced by the actinomycete strain B 4358 was identified as butyl-meta-cycloheptylprodiginine (4) by 1H, 13C and correlation via long range coupling NMR spectra. It shows striking spectroscopic similarities to butyl-ortho-cycloheptylprodiginine (1), the structure of which needs to be...

Zusammenfassung:A red pigment produced by the actinomycete strain B 4358 was identified as butyl-meta-cycloheptylprodiginine (4) by 1H, 13C and correlation via long range coupling NMR spectra. It shows striking spectroscopic similarities to butyl-ortho-cycloheptylprodiginine (1), the structure of which needs to be revised.
