A Prevost-type reaction under "wet" conditions upon the O-t-butyl-dimethylsilyl derivative of (+/-)-methyl 5β-hydroxycyclohexa-1,3-dienoate gives (+/-)-methyl 3α-acetoxy-4β-hydroxy-5β-t-butyldimethylsilyloxycyclohexene which may be readily deprotected to afford (+/-)-methyl shikimate in very high yield.Less selectivity is observed in a similar reaction upon the parent alcohol and when this compound is reacted under dry conditions the major product is (+/-)-methyl 4β,5β-epoxy-3β-acetoxycyclohexenoate.An analysis of Prevost reactions with exo and endo methyl 7-oxabicyclohept-5-en-2-oate is also described.

Specifically labeled shikimic acids with tritium or deuterium at posiions C-3 or C-4 were synthesized.Commercially available L-shikimic acid was converted to its 3- and 4-ketones, after suitable protection of the hydroxyl groups at C-4, C-5 and C-3, C-5.Reduction of the 3-keto or 4-keto-shikimic acid derivatives with sodium borodeuteride and deprotection gave mostly 3-D-epi-shikimic acid or 4-D-shikimic acid.An internally assisted inversion of the 3-D-epi-shikimic acid derivative and deprotection gave 3-D-shikimic acid.

The synthesis of 3-2H- and 4-2H-L-shikimic acids was accomplished starting from commercially available L-shikimic acid.
