2-Hydroxy-2,2-dimethylacetic acid ester derived heterobiaryl ethers containing 1,3,5-triazine substituents

Barluenga,Del Pozo,Olano

, p. 1529 - 1533 (1995)

The 1,3,5-triazines 3 were obtained from methyl 4-formylbenzoate (4) in a multistep synthesis by first introducing the ester unit under Williamson conditions. Subsequently, the 1,3,5-triazine ring was synthesized by reaction of isocyanates with 1,3-diazadienes obtained from N-silylimines.
