Novel reactions of 5-bromouracil derivatives with active methylene compounds.
5-Bromouracil derivatives (1) reacted with carbanions at room temperature to give 6-substituted uracils (6), 2,4-diazabicyclo[4,1,0] heptanes (8) and 2,4-diazabicyclo[4,3,0]nonane derivative (9), which depend largely upon the structure of the active methylene compounds employed for the generation of carbanions.
