A novel 6-amino-5-(substituted)pyrimidine-2,4(1H,3H)-dione derivatives, a method for preparing the same and use thereof

The present invention relates to novel 6-amino-5-(substituted)pyrimidine-2,4(1h,3h)-dione derivatives or a pharmaceutically acceptable salts thereof, to a synthesis method thereof, to a pharmaceutical composition comprising the same as an active ingredien

Reactivities of 6-amino-1,3-dimethyl-5-thioformyluracil toward nucleophiles and its application to synthesis of pyrido[2,3-d]pyrimidines

The reaction of the 5-thioformyluracil 1 with phenylhydrazine and various amines readily afforded the hydrazone 3a and Schiff bases 3b-d, respectively. Further, carbanions and Wittig reagents reacted with 1 to give pyrido[2,3-d]pyrimidines 4 and 9. The co
