All articles of this category The methodology based on the nucleophilic addition of stabilized carbon nucleophiles to N -alkylpyridinium salts constitutes a powerful tool for the synthesis of bridged indole alkaloids belonging to a variety of structural types, either tetracyclic (as vinoxine and ervitsine) or pentacyclic, in the latter case after closure of the tryptamine chain by cyclization upon the indole ring. Indole alkaloids - pyridinium salts - dihydropyridines
