The first syntheses of cruciferous indole phytoalexins (+/-)-1-methoxyspirobrassinin, (+/-)-1-methoxyspirobrassinol, (+/-)-1-methoxyspirobrassinol methyl ether as well as a new syntheses of phytoalexins (+/-)-spirobrassinin and cyclobrassinin were achieved by dioxane dibromide (DDB)-mediated spirocyclization of brassinin and its I-substituted derivatives.
