Synthesis of Five-Membered Heterocycles from Maleimides
Etzbach, Karl-Heinz,Elingsfeld, Heinz
, p. 449 - 452 (2007/10/02)
New heterocycles containing maleimide building blocks were prepared via 2-chloro-3-cyanomaleimide or 2,3-dichloromaleimides as key intermediates.Of the heterocyclic amines thus prepared, the following systems are useful as diazo components for preparing d
