  摘要：

  A method has been proposed for the synthesis of 2-alkyltetrazole-5-thiols. It was shown that these compounds are readily oxidized to the corresponding disulfides and their further functionalization has been studied.

  A number of orally active cephalosporins and penicillins with interesting biological activity were synthesized. Two of these, 7-[[[3,4-(methylenedioxy)phenyl]glycyl]amino]deacetoxycephalosporanic acid and 7-[[2-(2,3-dihydro-5-benzofuranyl)glycyl]amino]deacetoxycephalosporanic acid were considerably more active than cephalexin both in vitro and in vivo against staphylococcal and streptococcal infections.
