The First Synthesis of N-Alkyl-N-Arylthiocarbamoylacetates and Acetic Acids
摘要:
N-Alkyl-N-arylthiocarbamoylacetates, the key intermediates for the synthesis of novel antinephritic agents, have been prepared for the first time. Some of the esters were in turn hydrolyzed to the corresponding acids, An alternative, indirect synthetic route was also developed to prepare some unusual acids.

A series of quinoline-3-carbothioamides and their analogues was prepared via four synthetic routes and evaluated for their antinephritic and immunomodulating activities. The optimal compound 9g strongly inhibited the T-cell independent antibody production in mice immunized with TNP-LPS and was highly effective in two nephritis models, namely chronic graft-versus-host disease and autoimmune MRL/l mice

The novel title compounds have been prepared in high yield by an optimized amide coupling followed by a Dieckmann cyclization. Additionally, this new route is amenable to preparative scale synthesis.
