Popis: | 1. β-Ureido-β-(β-naphthyl)-propionic acid,β-(ω-phenylureido)-β-(β-naphthyl)-propionic acid, andβ-(N1-methylureido)-β-(β-nepthyl)propionic acid have been prepared, and have been converted into the corresponding 2,4-dioxo-hexahydropyrimidine derivatives 6-(β-naphthyl)-dihydrouracil, 3-phenyl-6-(β-naphthyl)-dihydrouracil, and 6-(β-nappthyl)-1-methyl-dihydrouracil. 2. Its amide was formed as a by-product of preparation ofβ-ureido-β-(β-napthyl)-propionic acid, and was also synthesized fromβ-amino-β-(β-napthyl)-propionic acid and sodium cyanate. 3. β-Ureido-β-(β-naphtyhl)-propionamide undergoes cyclization when heated. 4. Methyl-β-(ω-phenylureido)-β-(β-napthyl)-propionate has been prepared. 5. 2-Thio-6-(β-napthyl)-dihydrouracil,β-guanidino-β-(β-napthyl)-propionic acid, and 4-oxo-β-(β-naphthyl)-2-methyl-3,4,5,6-tetrahydropyrimidine have been synthesized. |
