  A Simple and Efficient Method for Synthesis of Benzothiazepine Derivatives

  摘要：

  A series of 1,5-benzothiazepines were synthesized using disulfides and alpha,beta-unsaturated carbonyl or nitrite compounds as reaction substrates. After reductive cleavage of the S-S bond of disulfides, the resulting thiols were reacted with alpha,beta-unsaturated carbonyl or nitrite compounds to generated seven-membered heterocyclic compounds. In the presence of ammonium thioglycolate, the Michael reaction occurred between disulfides (1) and 4-methyl-3-penten-2-one to give 2,2,4-trymethyl-3H-1,5-benzothiazepine derivatives in good yields. When ethyl acrylate or acrylonitrile was used as the Michael acceptor, 90-99% of (2-amino-phenylsulfanyl)propionitriles (3) and/or 92-99% of (2-amino-phenylsulfanyl)propionic acid ethyl esters (4) were produced. Subsequently, the 1,5-benzothiazepine compounds 5 and 6 were obtained due to the cyclization reaction.

  Dibenzothiazepine analogues containing lactam, amidine and imine moieties were prepared from 2-aminophenyl disulfides via one-pot S-arylation. The S-arylation involved cleavage of an S-S bond of disulfides and SNAr reaction in aqueous ammonia solution of L-cysteine to afford diaryl sulfides. Dibenzothiazepine analogues having lactam and amidine moieties were obtained by cyclization of the corresponding

  摘要 以2-氨基苯基二硫化物为原料，通过一锅S-芳基化反应制备了含有内酰胺、脒和亚胺部分的二苯并硫氮杂类似物。S-芳基化包括二硫化物的 SS 键断裂和 L-半胱氨酸氨水溶液中的 SNAr 反应，得到二芳基硫化物。具有内酰胺和脒部分的二苯并硫氮杂类似物是通过在酸性条件下环化相应的二芳基硫化物而获得的。2-溴-5-硝基苯甲醛的一锅S-芳基化通过分子内环化一步得到具有亚胺部分的二苯并硫氮杂类似物。获得了对金黄色葡萄球菌和大肠杆菌具有抗菌活性的化合物。

  The first example of molecular sieve-promoted TBHP-mediated direct oxidative thiolation of an sp3 C–H bond adjacent to a nitrogen atom with disulfides under metal-free conditions, which allows for preparation of numerous S,N-containing compounds, is presented. Moreover, diverse benzothiazoles and a fipronil analog can be synthesized through this strategy.
