Abstract: (E)-16-Aryl-substituted derivatives of tricyclic diterpenoids were synthesized by cross-coupling of isopimaric acid derivatives with substituted iodorenes catalyzed by palladium acetate in the presence of silver carbonate. Condensation of (E)-18-nor-4-(carboxyethyl)-16-(2-carboxyethyl)isopimar-7,15-diene dichloride with propargylamine hydrochloride leads to the corresponding dialkine, which readily reacts with diazide in the Cu(I) catalyzed cycloaddition (CuAAC) reaction, with the formation of macroheterocycli… Show more
