چکیده
|
An efficient and environmental friendly methodology for the synthesis of polysubstituted dihydro-2-oxypyrroles via a one-pot four-component domino condensation of dialkyl acetylenedicarboxylate,formaldehyde and amines (aromatic and aliphatic) at present of salicylic acid as an economical andnaturally green brønsted acid catalyst under ambient temperature with excellent yields and short reactiontimes is described. green, natural, inexpensive and non-toxic catalyst, easily separated with no columnchromatographic separation and highly efficient is an option for the simple synthesis of these rings.
