Base-catalysed ring opening of the acetonide of cis-exo-2,3-dihydroxy-6-methoxycarbonyl-7-oxabicycloheptane affords a stereo-controlled route to (+/-)-methyl 5-epishikimate and thence, by an elimination process, to (+/-)-methyl-cis-3,4-dihydro-3,4-dihydroxybenzoate.

A series of novel 4-phenylaminobenzofuro[2,3-d]pyrimidine derivatives had been prepared and assessed for their in vitro antiproliferative activities against three lung cancer cell lines (A549, H460 and H1975). The bioassay results showed most of the desig

experimental part, p. 78 - 84 (2010/12/20)
Candida antarctica lipase B (Novozym 435)-catalyzed transesterification on methyl (±)-3,4-di-O-acetyl-5-O-(tert-butyldimethyl)silyl-3-epi-shikimate worked highly regio- and enantioselective manner. Only (3R,4S,5S)-isomer reacted with an E value over 500,
COMPLEMENTARY SHORT SYNTHESES OF (+/-)-METHYL SHIKIMATE
Campbell, Malcolm M.,Kaye, Aston D.,Sainsbury, Malcolm,Yavarzadeh, Roya
, p. 1629 - 1630 (2007/10/02)
Two syntheses of (+/-)-methyl shikimate from the adduct of furan and methyl acrylate are described.One requires the regioselective hydroxylation of (+/-)-5β,6β-dihydroxy-O,O-isopropylidene-2-methoxycarbonylcyclohexa-1,3-diene and the other cis-dihydroxyla
BRIEF SYNTHESES OF (+/-)-METHYL SHIKIMATE, (+/-)-METHYL EPISHIKIMATE AND STRUCTURAL VARIANTS
Campbell, Malcolm M.,Kaye, Aston D.,Sainsbury, Malcolm,Yavarzadeh, Roya
, p. 2461 - 2470 (2007/10/02)
Two brief syntheses of (+/-)-methyl shikimate are described in a strategy which offers potentially flexible access to a range of analogues.New intramolecular rearrangement reactions of epoxides derived from methyl 7-oxabicyclohept-3-ene 6-carboxylate and methyl bicyclohept-3-ene 6 carboxylate are described.
SHIKIMIC ACIDS FROM FURAN; METHODS OF STEREOCONTROLLED ACCESS TO 3,4,5-TRIOXIGENATED CYCLOHEXENES
Rajapaksa, D.,Keay, B. A.,Rodrigo, R.
, p. 826 - 828 (2007/10/02)
Oxabicycloheptenes 1 and 2 are converted to 3,4,5-oxigenated cyclohexenes by stereocontrolled hydroxylations and epoxidations coupled with reverse-Michael cleavage of the oxabicyclo system.Three epimers of shikimic acid are synthesized by these methods.
AN IMPROVED SYNTHESIS OF (+/-)-METHYL SHIKIMATE THROUGH STEREOSELECTIVE CIS-DIHYDROXYLATION OF (+/-)-METHYL 5β-HYDROXYCYCLOHEXA-1,3-DIENOATE UNDER PREVOST'S REACTION CONDITIONS
Campbell, Malcolm M.,Sainsbury, Malcolm,Yavarzadeh, Roya
, p. 5063 - 5070 (2007/10/02)
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.
