  Efficient synthesis of (R)-ochratoxin alpha, the key precursor to the mycotoxin ochratoxin A

  摘要：

  Two new routes for the synthesis of enantiomerically pure ochratoxin alpha ((3R)-OT alpha) are presented, which is the key intermediate for the synthesis of ochratoxin A (OTA) by coupling reaction with the amino acid (L)-phenylalanine. The key step of both routes is the one pot directed ortho-metalation/alkylation/lactonization of unprotected and suitably functionalized aromatic carboxylic acids, using lithium tetramethylpiperidide (LIMP) and (R)-propylene oxide.

  (o-Hydroxyphenyl)methylphosphonic acids are readily obtained from o-(bromomethyl)- or o-(hydroxymethyl)phenols and trialkyl phosphites. Subsequent hydrolysis leads to the corresponding phosphonic acids. For a series of such compounds, the pKa values have been determined by potentiometry. Their dependence on additional substituents in the aromatic ring is discussed in terms of electronic and steric

  The invention comprises compounds of the formula <;FORM:0781413/IV (a)/1>; where R is alkyl, X is O or NH, Y is O or S, and Ar is aryl, which may have one or more alkyl, alkoxy, hydroxyalkyl, nitro or halogen substituents; the alkyl and alkoxy groups have not more than 4 carbon atoms. The compounds are prepared (1) by the action of H-Y-Ar on the appropriate pyrones or pyridones having a -CH2Z substituent where Z is a reactive ester group such as halide, sulphuric or sulphonic ester, preferably in a solvent at 50-100 DEG C. in the presence of a basic condensing agent, or (2) by the alkylation of the corresponding 5-hydroxy compounds. In addition the pyridones may be made from the pyrones by heating with ammonia. Examples show the preparation by method (1) of 2-aryloxymethyl-5 - methoxy - 4 - pyrones where aryl group is phenyl, b -naphthyl, and the following substituted phenyl groups:-chloro (3 isomers), 2:4-dichloro, 2:4:6-trichloro, pentachloro, methyl (3 isomers), dimethyl (6 isomers), 2:4:6-trimethyl, 2-methyl-4- and -6-chloro, 3-methyl-4-chloro, 4-methyl-2-chloro, 2-methyl-4:6-dichloro, 4 - methyl - 2:6 - dichloro, 2:4 - dimethyl-6-chloro, 3:5-dimethyl-4-chloro, 4-isopropyl, 4-cyclohexyl, 2- and 4-nitro, 2-methylol, 2:4 - dichloro - 6 - methylol, 2 - chloro - 4:6 - dimethylol, 4 - chloro - 2:6 - dimethylol, 4 - methyl - 2 - methylol, 4 - methyl - 2:6 - dimethylol, 2:5 - dimethyl - 4 - methylol, 3:4 - dimethyl - 6 - methylol, 3 - methoxy, and 2 - methoxy-4-, -5- and -6-methyl; also 2-(21-methylolphenoxymethyl) - 5 - ethoxy - 4 - pyrone and 2-(41-chlorophenylthiomethyl) - 5 - methoxy-4-pyrone.

It is also stated that Ar may also be ethylphenyl, ethoxyphenyl or hydroxy-ethyl-phenyl.ALSO:Compositions for use as plant growth regulants contain as active ingredient a compound of the formula: <;FORM:0781413/I/1>; where R is alkyl, X is O or NH, Y is O or S and Ar is aryl which may have one or more alkyl, alkoxy, hydroxyalkyl, nitro or halogen substituents; the alkyl and alkoxy groups have not more than 4 carbon atoms. The compositions may be in the form of powders, sprays, aerosols, emulsions or solutions in organic or aqueous organic solvents. There may also be present wetting agents, synergists and other plant growth regulants.
