A series of new, substituted 2,3-dihydropyran derivatives were synthesized by one-pot, three-component reactions of aldehydes, 1,3-dicarbonyl derivatives, and vinyl ethers catalyzed by ethylenediamine diacetate (EDDA) under solvent-free conditions. T

A convenient protocol for the synthesis of [1,4]oxazocane-5,8-dione heterocycles by direct cyclization using 2-substituted aminoethanols and divinyl succinate without any catalysts and additives was established. This strategy is quite simple and effe
