Abstract: Starting from methyl dehydroabietate, eight rosin-derived azo compounds were synthesized by nitration, reduction, diazonization and coupling reaction. The structures of eight azo compounds (1R,4aS)-methyl 6-((E)-(4-(dimethylamino)phenyl)diazenyl)-7-isopropyl-1,4a-di-methyl-8-nitro-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate (2a), (1R,4aS)-methyl-6-((E)-(5-cyano-2-hydroxy-1,4-dimethyl-6-oxo-1,6-dihydropyridin-3-yl)diazenyl)-7-isopropyl-1,4a-dimethyl-8-nitro-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate (2b), (1R,4aS)-meth-yl-((E)-(5-cyano-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazenyl)-7-isopropyl-1,4a-dimethyl-8-nitro-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate (2c), (1R,4aS)-methyl-7-((E)-(4-(dimethylamino)phenyl)diazenyl)-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate (3a), (1R,4aS)-methyl-7-((E)-(2-hydroxynaphthalen-1-yl)diazenyl)-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate (3b), (1R,4aS)-methyl-7-((E)-(4-(dimethylamino)phenyl)diazenyl)-1,4a-dimethyl-9-oxo-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate (5a), (1R,4aS)-methyl-7-((E)-(2-hydroxynaphthalen-1-yl)diazenyl)-1,4a-dimethyl-9-oxo-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate (5b) and (1R,4aS)-methyl 6-bromo-7-((E)-(2-hydroxynaphthalen-1-yl)diazenyl)-1,4a-dimethyl-9-oxo-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate (5c) were characterized by MNR, IR and elemental analysis. The yields were 57%, 33%, 30%, 36%, 39%, 39%, 40% and 38%, respectively. Comparing with methyl dehydroabietate, their UV maximum absorption wavelength were 420, 454, 457, 541, 493, 549, 482 and 550 nm in chloroform, which were increased 200, 234, 237, 321, 273, 329, 262 and 330 nm, respectively.
