摘要:
cis-Cyclohexa-3,5-diene-1,2-diol 2, the product of oxidation of benzene by mutants of Pseudomonas putida, was transformed into optically pure 4 in a sequence involving asymmetrization of meso-diol 3 in organic media with Pseudomonas cepacia lipase. Alcohol 4 was converted into the title compounds by processes utilizing alpha-iodination of the derived enones 8 and 9 followed by Pd0-catalysed coupling of the alpha-iodoenones with 2-tributylstannylfuran and RuO4-catalysed oxidation of the 2-furyl groups to carboxylic acids.
