Cyclic homologs of xanthines. I. Imidazo[4,5-e][1,4]diazepine-5,8-diones
Bridson,Weirich
, p. 1179 - 1182 (1988)
A useful synthetic approach to variously alkylated 4,5,7,8-tetrahydro-6H-imidazo[4,5-e][1,4]diazepine-5,8-diones is reported. These compounds are potentially interesting cyclic homologs of pharmacologically important alkylxanthines.
