Journal ArticleDOI
Molecular diversity of spirooxindoles. Synthesis and biological activity
TL;DR: This review focuses on the various strategies for the enantioselective synthesis of spirocyclic oxindoles relying on reports over the past decade and from earlier work.
Journal ArticleDOI
Synthesis and molecular structure of spirocyclic 2-oxindole derivatives of 2-amino-4H-pyran condensed with the pyrazolic nucleus
R. G. Red’kin,Leonid A. Shemchuk,Valentine P. Chernykh,Oleg V. Shishkin,Svetlana V. Shishkina +4 more
TL;DR: In this article, a three-component condensation of isatins with 3-methyl-pyrazolone-5 and respective methylene active nitriles in the presence of basic catalysts was proved unambiguously by X-ray diffraction.
Journal ArticleDOI
Synthesis of fused 2′-amino-3′-R-spiro-[indole-3,4′-pyran]-2(1H)-ones
TL;DR: An efficient one-pot procedure for the synthesis of fused 2′-amino-3′-R-spiro-[indole-3,4′-pyran]-2(1H)-ones via base-catalyzed three-component condensation of isatins with the corresponding nitriles and 1,3-diketones was proposed in this article.
Journal ArticleDOI
An efficient, three-component synthesis and molecular structure of derivatives of 2-amino-3-R-6-ethyl-4,6-dihydropyrano[3,2-c][2,1]benzothiazine-5,5-dioxide spirocombined with a 2-oxindole nucleus
Leonid A. Shemchuk,Dmitry A. Lega,R. G. Red’kin,Valentin P. Chernykh,Oleg V. Shishkin,Svetlana V. Shishkina +5 more
TL;DR: Spiro as mentioned in this paper synthesized three-component interaction of benzo[c][2,1]thiazin-4-on 2,2-dioxide with corresponding isatins and appropriate methylene active nitriles in the presence of a base as a catalyst.
Journal ArticleDOI
Synthesis and chemical properties of new derivatives of 3a',6a'-dihydro-2'H-spiro- [indole-3,1'-pyrrolo[3,4-c]pyrrole]-2,4',6'(1H,3'H,5'H)-trione

TL;DR: A series of new 3a',6a'-dihydro-2'H-spiro[indole-3,1'-pyrrolo[3,4-c]pyrrole]-2,4',6'(1H,3'H,5'H)- triones has been synthesized by cycloaddition of azomethine ylides, obtained from isatins and acyclic aliphatic and sulfur-containing α-amino acids, to maleimides.
