Thiol-dependent DNA cleavage by aminomethylated Beaucage's reagent

Aminomethylated Beaucage's reagent 1 was found to be more potent than 3H-1,2-benzodithiol-3-one 1,1-dioxide (Beaucage's reagent) in causing DNA cleavage. The current study demonstrated the importance of the amino functionality in enhancing DNA-cleaving ac

Substituent effects on the reactivity of benzo-1,2-dithiolan-3-one 1-oxides and their possible application to the synthesis of DNA-targeting drugs

The efficiency of polysulfane product generation has been investigated for n-propyl thiol reactions with ortho- and para-substituted benzo-1,2-dithiolan-3- one 1-oxides in acetonitrile-water (7:3) mixtures. The reaction is facilitated by reducing the electron density at the para position or by placing substituents bearing lone pair electrons ortho to the dithiolanone-oxide (S1) reaction center. Through-space and through-bond effects both contribute to the conversion of polysulfane products.

Synthesis of some 4-oxothiochromenes and related compounds

Thiosalicylic acids react with 2-substituted N,N-dialkyl acetamides to give 3-substituted-N,N-dialkyl-2-amino-4-oxothiochromenes 13. N-Alkyl 2-piperidone and analogous caprolactams give derivatives of 1,2,3,4-tetrahydrothiochromeno[2, 3-b]pyridin-5-one 16

Conformational Behaviour of Medium-sized Rings. Part 10. Dithiosalicylides and Trithiosalicylides

The trithiosalicylide derivatives (8)-(11) have been synthesised and shown by temperature-dependent 1H n.m.r. spectroscopy to exist in solution as ring inverting (35a)(35b) enantiomeric helical conformations with trans-thioester linkages.The free energies of activation for these conformational changes are ca. 10 kcal mol-1 higher than those for the similar process in the corresponding trisalicylides.In contrast with the trisalicylides, the trithiosalicylides can only ring invert between enantiomeric helical conformations via intermediates containing a cis-thioester linkage.The dithiosalicylide derivatives (3)-(7) have been synthesised; the temperature dependence of the 1H n.m.r. spectrum of di-o-thiothymotide (7) has been interpreted in terms of ring inversion (40a)(40b) between enantiomeric boat conformations.Comparison of the ΔG value of 24.6 kcal mol-1 for this conformational change with that of 17.7 kcal mol-1 previously obtained for di-o-thymotide (41) suggests that cis-thioester linkages are subject to more resonance stabilisation than are cis-ester linkages.

"Mercaptan-Tail" Porphyrins: Synthetic Analogues for the Active Site of Cytochrome P-450

The synthesis and characterization of a series of tetraarylporphyrins which bear covalently attached alkyl and aryl mercaptans designed to serve as axial ligands are described.The coordination chemistry of the iron(II) complexes of these "mercaptan-tail" porphyrins has been investigated by 1H NMR, IR, and electronic absorption spectroscopy, magnetic circular dichroism, and magnetic susceptibility measurements.Ferrous complexes of the alkyl mercaptan-tail porphyrins appear to remain four-coordinate, intermediate spin (S = 1) in solution.The situation is less clear in the case of appended aryl mercaptans and a "tail-on/tail-off" equilibrium is implicated.In the presence of carbon monoxide, however, binding of thiol trans to CO is observed in both the alkyl and aryl cases.By the addition of an appropriate base, six-coordinate mercaptide-Fe(II)-CO complexes can be generated; these reproduce quite well the characteristic absorption and MCD spectra of cytochrome P-450, suggesting that such compounds are indeed viable models for the active site of cytochrome P-450.
