  Hydrazine derivatives in the synthesis of linear and heterocyclic compounds

  摘要：

  N-Siloxycarbonylation, transamination, carboxylation, silylation, and condensation of N,N-dimethylhydrazine, 1-methyl-1-[2-(1-methylhydrazino)ethyl]hydrazine, N-methyl-2-(1-methylhydrazino)ethanamine, and some their trimethylsilyl derivatives resulted in the formation of previously unknown linear and heterocyclic compounds.

  日期：——

  Regioselective cyclocondensations of several hydrazones with chlorocarbonylsulfenyl chloride afforded 1,3,4-(3H,6H)-thiadiazin-2-one derivatives and 3(2H)-(dimethylamino)thiazolones. The -COS- linkage was effectively incorporated into the S,N-containing heterocycles.
