  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.
