  Synthesis and antisecretory and antiulcer activities of derivatives and analogs of 2-(2-pyridyl)tetrahydrothiophene-2-carbothioamide

  摘要：

  New thioamide derivatives of 2-(2-pyridyl)tetrahydrothiophene-2-carbothioamide (29) and related compounds (in which the tetrahydrothiophene ring was replaced by tetrahydrothiopyran, tetrahydrofuran, 1,3-dithiane, or 1,3-oxathiane and where the pyridine ring was replaced by other nitrogen heterocycles) were synthesized and tested for their antisecretory and antiulcer activities. These thioamides were prepared according to one of the following methods: reaction of an isothiocyanate with the carbanion of the corresponding cyclic precursor (for secondary thioamides); reaction of ammonia or an amine with the dithio ester prepared from the same precursor (for primary, secondary, and tertiary thioamides). These thioamides were evaluated by the Shay method to measure their antisecretory activity and by the stress-induced-ulcer method to test their antiulcer activity. Structure-activity relationships are discussed. N-Methyl-2-(2-pyridyl)tetrahydrothiophene-2-carbothioamide (R.P. 40749, 30) exhibited activities that were at least 10 times higher than those reported for cimetidine.

  通过光氧化还原和弱 Brønsted 碱催化硫醚的 α-杂芳基化

  摘要：

  我们报告了硫醚对 α-硫代烷基自由基的 C-H 活化以及它们与N-甲氧基杂芳鎓盐的加成，用于氧化还原中性合成 α-杂芳族硫醚。研究与两步活化机制一致，其中通过光氧化还原催化剂将硫醚氧化为硫化物自由基阳离子，然后通过弱 Brønsted 碱催化剂进行 α-C-H 去质子化以提供 α-硫代烷基自由基。此外，N-甲氧基杂芳鎓盐作为甲氧基自由基的来源，有助于α-硫代烷基自由基的产生和再生光氧化还原催化循环的牺牲氧化剂，发挥了额外的作用。

  thioethers to α-thio alkyl radicals and their addition to N-methoxyheteroarenium salts for the redox-neutral synthesis of α-heteroaromatic thioethers. Studies are consistent with a two-step activation mechanism, where oxidation of thioethers to sulfide radical cations by a photoredox catalyst is followed by α-C–H deprotonation by a weak Brønsted base catalyst to afford α-thio alkyl radicals. Further,
