The preparation method comprises the following steps: 1) mixing an o-amino formonitrile heterocyclic compound and a catalyst to form a mixture, wherein the catalyst is [HDBN][TFE]; 2) in a CO2 environment, heating the mixture and reacting; 3) when the temperature is reduced to room temperature, adjusting the pH value to neutrality, and extracting, separating and collecting the an organic phase; drying, filtering and then vaporizing; performing column chromatography separation to obtain the heterocyclicpyrimidinedione compound. The preparation method disclosed by the invention has the advantages of low cost, environmental friendliness, simple preparation process and wide application range of substrate.

One or two-step Bohlmann-Rahtz heteroannulation of 6-aminouracil derivatives for the synthesis of pyrido[2,3-d]pyrimidines

The Michael addition-cyclodehydration of a 6-aminouracil and alkynone proceeds to give 5-deazapterin derivatives with total control of regiochemistry. This simple and facile cyclocondensation process is catalyzed by zinc(II) bromide or ytterbium(III) trifluoromethanesulfonate at 110°C, providing the heteroannulated products in up to 94% yield.
