Heterocyclization reactions of 6-aryl-2,2-dimethyl-1,3-dioxin-4-ones with ?-oxoketeneaminals
摘要:
During thermolysis 6-aryl-2,2-dimethyl-1,3-dioxin-4-ones react with alpha-mono- and alpha,alpha-dioxoketene aminals to yield 3-acetyl-6-aryl-2-benzoylamino-4-pyridones or 6-aryl-2-methylene-4-pyrimidones, respectively. A scheme of the formation of pyrido[2,3-d]pyrimidines from dioxinones and 1-amino-1-benzoylamino-1-bytene-3-one has been suggested.

A series of new trichloromethyl- and alkoxy-substituted pyrido[2,3-d]pyrimidine derivatives were obtained from trichloromethyl-substituted pyrimidines with vicinal amino and acyl groups synthesized based on the reaction of trichloroacetonitrile with β-diketone diaminomethylidene derivatives.
