3. LEARNING OBJECTIVE
6/16/2023
• To know about traube synthesis
• To know the mechanism involve in traube purine synthesis
• To learn application of traube purine synthesis

4. • This reaction was 1st introduced by taube in 1900
• Traube purine synthesis is the most versatile method for introduction of carbon
fragment to bridge the nitrogen from atoms of the amino group C-5 and C-6 of
pyrimidine ring .
• The pyrimidines of high purity as starting materials should be used for this reaction.

5. Basic reaction
6/16/2023
It is the most widely used for the synthesis of purine. 4,5-Diaminopyrimidine on formylation
followed by cyclodehydration provide purine. 4,5-Diaminopyrimidine is synthesised from 4-
aminopyrimidine other formic acid derivatives like formamide, formamidine , orthoformic esters
etc.

6. Mechanism of Taube purine synthesis

7. Synthetic application
6/16/2023
Adenine can be prepare by the interaction of 6-chloro-4,5-diamonopyridine with diethoxy
methyl acetate to furnish 6-Chloropurine which on subsequent which on subsequent
animation with ammonia yield the desired product.

8. 6/16/2023
The procedure involve the reaction of 4-amino-5 –nitrosopyrimidine with formic acid in the
presence of Raney nickel to afford purine. This regarded as a convenient route for the purine
synthesis
Synthetic application

9. Conclusion
6/16/2023
The Traube purine synthesis is 4,5-Diaminopyrimidine on formylation followed by
cyclodehydration provide purine. 4,5-Diaminopyrimidine is synthesised from 4-
aminopyrimidine. this reaction may undergo only the formylation at the 5‐amino group without
further cyclization
