Abstract:


An effective one-pot synthesis of dialkoxyphosphoryl-2-oxo-2H-pyran derivatives by three-component reaction of alky bromides and dialkyl acetylenedicarboxylates in the presence of trialkyl phosphite is described. The reactions were performed under solvent-free conditions at 50°C and neutral conditions and provided good yields of products.

Keywords:

2H-pyran, Alky bromide, dialkyl acetylenedicarboxylates, green chemistry, three-component reaction, trialkyl phosphite.
