1-trimethylsilylpyrrole-2,5-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Analogously to Example Z23, method I, 21.9 g (0.12 mol) of 1-(tert.-butyloxycarbonylamino)-1,3-pentadiene are reacted with 20.3 g (0.12 mol) of N-trimethylsilylmaleimide, and the product is subsequently reduced with 15.2 g (0.4 mol) of lithium aluminium hydride. The crude product is recrystallised from tetrahydrofuran. The crude product is recrystallised from tetrahydrofuran

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
