Novel and Efficient Syntheses of Four Useful Shikimate- derived Epoxy Chiral Building Blocks via Cyclic Sulfite Intermediates
All of the four stereoisomers of methyl 4,5-epoxy-3-hydroxy-cyclohex-l-ene-carboxylate (la--ld) are useful chiral building blocks. Novel and efficient syntheses of these four epoxy chiral building blocks from naturally abun- dant (--)-shikimic acid (2) via cyclic sulfite intermediates are described...

description | All of the four stereoisomers of methyl 4,5-epoxy-3-hydroxy-cyclohex-l-ene-carboxylate (la--ld) are useful chiral building blocks. Novel and efficient syntheses of these four epoxy chiral building blocks from naturally abun- dant (--)-shikimic acid (2) via cyclic sulfite intermediates are described in this article. The targeted compound (3R,4R,5S)-la was synthesized via four steps from (--)-shikimic acid in 79% overall yield. The other three targeted compounds (3S,4R,5S)-lb, (3S,4S,5R)-1c and (3R,4S,5R)-ld were synthesized via seven steps from (--)-shikimic acid in 56%, 64% and 65% overall yields, respectively. |
