NOVEL REACTION OF 5-NITRO(OR CARBAMOYL)URACIL DERIVATIVES WITH AMINES. THERMAL EXCHANGE REACTION OF N1-PORTION OF THE URACILS FOR AMINES VIA RING-OPENING AND RING-CLOSURE PROCESSES

Article abstract of DOI:10.1016/S0040-4039(00)84770-X

The reaction of 1,3-disubstituted uracils possessing an electron withdrawing group at the 5-position with amines induced exchange of N1-portion of the uracil ring for amines.This reaction was accelerated by substitution of phenyl groups at the N1-position.
