Enantiospecific synthesis of (−)-5-epi-shikimic acid and (−)-shikimic acid

Journal of the Chemical Society, Perkin Transactions 1, 1997
Diastereoselective reaction of 2,3-O-isopropylidene-D-ribose with allylmagnesium chloride gave a 5∶1 mixture of triols 4 and 5, which were then converted to nitrones 8 and 9. Intramolecular nitrone cycloaddition gave the isoxazolidines 10 and 11, which on acetylation gave the corresponding acetates 12 and 13 which were separated by repeated ...

Production of shikimic acid

Biotechnology Advances, 2012
Shikimic acid is a key intermediate for the synthesis of the antiviral drug oseltamivir (Tamiflu®). Shikimic acid can be produced via chemical synthesis, microbial fermentation and extraction from certain plants. An alternative production route is via biotransformation of the more readily available quinic acid.

Polymorphism of shikimic acid

China Journal of Chinese Materia Medica, 2016
This study was performed to systematically investigate the polymorphism of shikimic acid. Through optimizing the recrystallization solvent, solvent volume, recrystallization temperature, time and pressure, three crystal forms were discovered and prepared.

Shikimic Acid Pathway

2014
Of the identified biosynthetic paths, shikimic acid pathway plays a very important role in providing precursors of a large number of aromatic compounds of diverse skeletal patterns and substitutions. Chorismic acid, an important branching point product in the shikimic acid pathway also serves as an important precursor. Natural products with C 6 –C 1 or

Carcinogenicity of bracken and shikimic acid

Nature, 1974
SINCE our initial reports of the carcinogenic potential of bracken for rats and mice1,2 part of our work has been directed towards the isolation of the causative factor(s). The assays used have included acute toxicity testing in mice (orally and intraperitoneally (i.p.)) and mutagen trials with Drosophila and mice, as well as long term cancer induction

Shikimic Acid in Grass

Nature, 1955
IN a paper describing, inter alia, the isolation of quinic acid from grass1, it was suggested that one of the acids (termed ‘acid B’) present in the grass extracts might be shikimic acid or a closely allied acid. Acid B appeared to be identical with ‘acid G’ found by Davies and Hughes2 in grass and stated by them to be a monobasic acid of relatively ...
