  5-Substituted 3-thiophenesulfonamides as carbonic anhydrase inhibitors

  摘要：

  A series of 5-substituted 3-thiophenesulfonamides was prepared from 4-bromo-2-thiophene carboxaldehyde. Several of these compounds inhibited carbonic anhydrase II in vitro at concentrations of less than 10 nM. In the ex vivo assay, these compounds have inhibitory values in the 25-81% range. Additionally, none of these compounds exhibit sensitization potential as determined by in vitro measurement of cysteine reactivity.

  Relative Basicities of ortho-, meta-, and para-Substituted Aryllithiums

  摘要：

  The relative basicities of aryllithiums bearing methoxy, chlorine, fluorine, trifluoromethyl and trifluoromethoxy substituents at the ortho, meta, and para positions have been assessed. To this end, two aryllithiums of comparable basicity were equilibrated together with the corresponding bromo- or iodoarenes in a 1: 2 mixture of pentanes with tetrahydrofuran at -50, -75, or -100 degrees C. The "basicity" (protodelithiation) increments Delta Delta G derived from the equilibrium constants are linearly correlated with the relative protonation enthalpies of the corresponding aryl anions in the gas phase. However, the correlation factor proves to be position-dependent. Compared with "naked" aryl anions, the basicity of aryllithiums mirrors the effects of ortho, meta, and para substituents to the extent of 36%, 30%, and 25%, respectively.

  Solutions of the title compounds R-Ti(OR′)3 (1) are generally available from organolithium (or magnesium) derivatives according to equation 1. It is shown (Table 1) that some heterosubstituted organotitanium compounds are more stable thermally than their lithium counterparts. The reagents 1 are highly selective carbonylophiles (Tables 1 and 2), their reactivity can be modified by variation of the R′O-group
