Water as the Green Media for the Synthesis of Isoquinoline Derivatives

An efficient synthesis of isoquinoline-2,3-dicarboxylates is described via one-pot reactions of isoquinoline and alkyl bromids with dialkyl acetylenedicarboxylates in water at 70oC. The mild reaction conditions and high yields of the products exhibit the good synthetic advantage of these methods.

Nanocrystalline SiO2–HClO4: A novel, efficient and green catalyst for the three-component synthesis of pyrimidine derivatives

Nanocrystalline SiO2–HClO4, as a newly reported catalyst, has been used as an efficient and reusable catalyst for the synthesis of pyrimidine derivatives. The procedure can be successfully applied to the efficient synthesis of mono substituted pyrimidine derivatives, using triethyl orthoformate, ammonium acetate, methyl ketone derivatives. In practice, this method is a combination of a satisfac...
