Relevant academic research and scientific papers

Synthesis and structural characterisation of ring B oxidised derivatives of dehydroabietic acid

The synthesis and structural characterisation of some new derivatives of dehydroabietic acid, oxidised in the 6 and 7 positions of ring B, are described. Other known derivatives were exhaustively characterised for the first time and the previous NMR assig

Stereoselective partial synthesis of (+)-pisiferic acid

(±)-Pisiferic acid (1), an antibiotic active against Gram-negative and Gram-positive bacteria, was synthesized starting from dehydroabietic acid (2) or abietic acid (26). The terpene ring system was functionalized and a Barton reaction used to oxidize Me(20). The intermediates of this photochemical reaction were isolated and characterized.

Bromination of Resin Acid Derivatives

Radicalic bromination of 1, 2, and 3 leads to products with halogen in the isopropyl group.The corresponding olefins are obtained by elimination of HBr. - Keywords: 17,19-Dinoratis-15-ene-4,13,14-tricarboxylic acid, 16-(1-methylethyl), cyclic-13,14-anhydride (4α,8α,12α) and derivatives; 17,19-Dinoratis-15-ene-4,13,14-tricarboxylic acid, 16-(1-methylethyl), 4,13,14-trimethylester (4α,8α,12α,13β,14α) and derivatives; 1-Phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-, and derivatives
