Main Article Content
Abstract
The 4-oxo-N,2,6-triphenylpiperidine-3-carboxamides (3a-f) were synthesized using arylaldehydes, ammonium acetate and acetoacetanilide, which in turn converted into 5,6,7,8-tetrahydro-4-hydroxy-5,7-diarylpyrido[4,3-d]pyrimidin-2(3H)-ones (4a-f), 2-amino-5,6,7,8-tetrahydro- 5,7-diarylpyrido[4,3-d]pyrimidin-4-ols (5a-f) by condensing with guanidine carbonate and urea respectively.
