Abstract

The cruciferous phytoalexin brassilexin 3 has been synthesized in four steps from indoline-2-thione via 3-(aminomethylene)indole-2-thione 2, a metabolic intermediate of the detoxification pathway of the phytoalexin cyclobrassinin 1; in addition, the phytoalexin brassicanal A 8 has been synthesized in two steps from 2-indolinethione.
