The regioselective synthesis of spirooxindolo pyrrolidines and pyrrolizidines via three-component reactions of acrylamides and aroylacrylic acids with isatins and α-amino acids

open access: yesBeilstein Journal of Organic Chemistry, 2014
The regioselective three-component condensation of azomethine ylides derived from isatins and α-amino acids with acrylamides or aroylacrylic acids as dipolarophiles has been realized through a one-pot 1,3-dipolar cycloaddition protocol.

Electric field induced effects in Y3N@[C80]6- anionic solid [PDF]

open access: yes, 2015
By measuring the i−vi−v characteristics of Y3N@[C80]6− anionic solid at various temperatures and electric field strengths, four conducting phases with i∝vi∝v , i∝v2i∝v2 with low resistance, i∝v4i∝v4 and i∝v2i∝v2 with high resistance were observed. First,

Synthesis of Dihydrouracils Spiro-Fused to Pyrrolidines: Druglike Molecules Based on the 2-Arylethyl Amine Scaffold

open access: yesMolecules, 2010
The synthesis of a small library of dihydrouracils spiro-fused to pyrrolidines is described. These compounds are synthesized from b-aryl pyrrolidines, providing products with the 2-arylethyl amine moiety, a structural feature often encountered in ...
