17O NUCLEAR MAGNETIC RESONANCE SPECTROSCOPIC STUDY OF SUBSTITUTED PHTHALIC ANHYDRIDES AND PHTHALIDES

17O chemical shift data (natural abundance) for 3-substituted phthalic anhydrides and 4- and 7-substituted phthalides in acetonitrile at 75 deg C are reported.Steric interactions of substituents ortho to the carbonyl groups result in deshielding effects (9-22 ppm) relative to parent compounds regardless of the electronic character of the substituents.Factors contributing to the deshielding effects are discussed.The relationship between 17O chemical shifts and regiochemistry of the phthalic anhydrides is discussed.

On the regioselectivity of the condensation of stabilized phosphoylids with 3-substituted phthalic anhydrides

Condensations of stabilized phosphorane 1 with 3-substituted phthalic anhydrides were investigated.The importance of various effects influencing regio- and stereoselectivity of these reactions is discussed.It is proposed that the oxygen atom on the substituents in position 3 can act as a Lewis base toward the electron-deficient phosphorus of the ylid.The resulting complexation stabilizes the transition state for the reacction at the ortho carbonyl group, thus offsetting the usual steric and “push” effects, wich favour attack at the meta carbonyl function. – Key words: Wittig condensations, phthalic anhydrides, regioselectivity, stereoselectivity.

Regioselective Addition of Grignard Reagents to 3-Methoxy- and 3-Nitrophthalic Anhydride

The regioselectivity in the addition of the grignard reagents 5a and 6a to the anhydrides 1 and 2 is determined by the solvent system: in a highly selective manner (3:97), the meta carbonyl group is attacked in tetrahydrofuran/tetramethylethylenediamine, while predominant, but relatively unselective (maximum 78:22) addition to the ortho carbonyl group is observed in diethyl ether.The influence of the solvent system on the regioselectivity is discussed.The LUMO-coefficients of the carbonyl carbon atoms in 1 and 2 were calculated.

7-(4,6-dimethoxypyrimidinyl)oxy- and -thiophthalides as novel herbicides: Part 1. CGA 279 233: A new grass-killer for rice

A series of novel types of 7-(4,6-dimethoxypyrimidin-2-yl)oxy – and -thio-3-methyl-1 (3H)-isobenzofuranones were discovered at Dr R Maag AG. From the thio-isobenzofuranyl series, CGA 279 233 – BSI-proposed common name pyriftalid – was chosen for further development as a grass herbicide for use in rice. General synthetic approaches to these new phthalic acid-derived compounds are given, with emphasis on the synthesis of pyriftalid and its physico-chemical behaviour.

Enantioseletive Fluorination of 3-Functionalized Oxindoles Using Electron-rich Amino Urea Catalyst

An enantioselective fluorination of 3-functionalized oxindoles using electron-rich amino urea catalyst is described. Various 3-functionalized 3-fluoro-2-oxindoles were obtained in good yields and enantio-selectivity. The resulting enantioenriched 3-methylene nitrile 3-fluoro-2-oxindole product was found to inhibit indoleamine 2,3-dioxygenase considerably. (Figure presented.).

Synthesis of phosphonate 3-phthalidyl esters as prodrugs for potential intracellular delivery of phosphonates

A new prodrug approach for intracellular delivery of phosphonates was developed via the synthesis of 3-phthalidyl esters of 1- naphthalenemethylphosphonate. This approach is advantageous over the traditional acyloxymethyl phosphonate prodrugs, because these prodrugs do not generate formaldehyde and have improved plasma half-lives.
