Behaviour of terpene peroxides from abietic acid in the presence of heme and non-heme iron(II)

In aqueous acetonitrile with FeCl2 or hemin/L-cysteine, a peroxide (4) obtained from abietic acid by photosensitized air oxidation undergoes rearrangement to give a diepoxide and two spiro compounds as major products. (C) 2000 Elsevier Science Ltd.

Sulfonium sulfonate photoacid generator synthesized from abietic acid and synthesis method of sulfonium sulfonate photoacid generator

The invention discloses a sulfonium sulfonate photoacid generator synthesized from abietic acid, and relates to the field of photoacid generators. The sulfonium sulfonate photoacid generator has a structural formula shown in the specification, in the formula, R1 is an oxygen-containing linking group, and R2 is a fluoroalkyl group. The photoacid generator can reduce the diffusion of the photoacid generator, improve the edge roughness, reduce the line width roughness and improve the resolution; the photoacid generator is more transparent under 193 nm, and exposure under a 193 nm light source is facilitated; the etching resistance is excellent; the photoacid generator is balanced in hydrophilicity and lipophilicity, has proper adhesive force and excellent solubility, is more uniform in dissolution, and is simple in synthetic route.

Total Synthesis of Nominal ent-Chlorabietol B

The nominal enantiomer of chlorabietol B was regio- and stereoselectively synthesized from (-)-abietic acid in 13 steps. Key features of the synthesis involved an oxidative [3+2] cycloaddition to install the dihydrobenzofuran moiety and an Aldol reaction, followed by elimination and reduction steps to introduce the long chain with three cis double bonds. However, obvious differences in the NMR spectra of the synthetic and natural samples suggested that the proposed structure of chlorabietol B should be revised carefully.

A Micellar Catalysis Strategy for Amidation of Alkynyl Bromides: Synthesis of Ynamides in Water

Copper-catalyzed amidation of alkynyl bromides can be carried out in water for the first time, which is made possible by a micellar catalysis strategy using rosin-based surfactant APGS-550-M. The surfactant can be easily prepared from natural abundant biomass, resin acids. Studies as to substrate scope and reaction aqueous medium recycling showcase the ease and sustainability of this technology.
