Bobalek, Antimicrobial Performance of Tri-and Tetrachloro-4 (methylsulfonyl
) Pyridines as Industial Preservatives.
metabolites of PCBs and DDE in human milk in Sweden, 1972-1992.
[Et.sub.3]N (1.33 ml, 9.5 mmol) and methylsulfonyl
chloride (MsCl) (1.15 g, 10 mmol) were added to a solution of dioxepane 3 (2.12 g, 9.4 mmol) in 20 ml of C[H.sub.2][Cl.sub.2].
The main generated by-products are 4-(methylsulfonyl
)-2-nitrobenzoic acid, 1,3-diketo 3-(2-nitro-4-methylsulfonylphenyl)butanoic acid, and 5,7-diketo7-(2-nitro-4-methylsulfonylphenyl)-heptanoic acid (Figures 8 and 9).
The synthetic compounds derived from 6-MITC include 6-(methylsulfenyl)hexyl isothiocyanate (I7447) and 6-(methylsulfonyl
)hexyl isothiocyanate (I7557).
)pyrrolidine-1-carboxylate (1, Method E) was isolated as pale yellow oil using triethylamine as the base (>99%); [sup.1]H NMR [delta] 5.16 (m, [sup.1]H, diastereotopic ring 3-CH); 3.30-3.58 (m, 4H, ring 2 and 5-C[H.sub.2]); 2.92 (s, 3H, mesylate C[H.sub.3]); 1.96-2.15 (m, 2H, ring 4-C[H.sub.2]), 1.32 (s, 9H, t-BOC C[H.sub.3]); [sup.13]C NMR [delta] 28.4, 28.5, 32.0, 32.6, 38.6, 38.7, 43.7, 43.9, 46.2, 51.9, 52.2, 79.8, 80.4, and 154.2; IR (film) 3488, 2979, 1694, 1410, 1366, 1170, 1118, 957, 924, and 900 [cm.sup.?1].

)phenyl)-2-tosyl-3-(3,4,5-trisubstituted phenyl)prop-2-en-1-ones with 2-Aminothiophenol in Refluxing Toluene Using Catalytic Amounts of Trifluoroacetic Acid.
Abbreviations used: EDTA, ethylenediamine tetraacetate; PAGE, polyacrylamide gel, electrophoresis; PMSF, phenyl- methylsulfonyl
fluoride; SDS, sodium dodecyl sulphate
)acetamide (NS-304), an orally available and longacting prostacyclin receptor agonist prodrug.
