N. Armesto et al., Efficient synthesis of (-)-methyl 3-epi-shikimate and methyl 3-eqi-quinateby one-pot selective protection of trans-1,2-diols, TETRAHEDR L, 41(45), 2000, pp. 8759-8762
trans-1,2-Diol protections of shikimic and quinic acids have been achieved
by in situ formation of the protecting group (2,2,3,3-tetramethoxybutane).
The synthetic utility of the protected derivatives is demonstrated by the p
reparation of (-)-methyl 3-epi-shikimate and methyl 3-epi-quinate through a
new and efficient route from the parent acids. (C) 2000 Published by Elsev
