Iron(III)-Catalyzed Arylation of Spiro-Epoxyoxindoles with Phenols/Naphthols towards the Synthesis of Spirocyclic Oxindoles.

Only registered users can translate articles

An efficient and highly regioselective iron(III)-catalyzed Friedel-Crafts-type arylation of spiro-epoxyoxindoles with phenols was developed for rapid access to 3-(3-indolyl)-oxindole-3-methanols, which could be further elaborated into benzofuranyl-spirooxindoles under Mitsunobu conditions. When

Cascade arylalkylation of activated alkenes: synthesis of chloro- and cyano-containing oxindoles.

Only registered users can translate articles

The general method for the oxidative cyclization of arylacrylamides with dichloromethane or acetonitrile has been developed. The reactions described provide novel access to chloro- and cyano-containing oxindoles in good to moderate yields that allow the direct formation of a C-C bond and the

Anticancer activity of the Uncaria tomentosa (Willd.) DC. preparations with different oxindole alkaloid composition.

Only registered users can translate articles

The activity of Uncaria tomentosa preparations on cancer cells was studied using in vitro and in vivo models. IC (50) values were calculated for preparations with different quantitative and qualitative oxindole alkaloid composition: B/W(37) --bark extracted in water at 37 °C, B/W(b)--bark extracted

Only registered users can translate articles

Indolin-2-one (oxindole), (I), undergoes a Knoevenagel condensation with ferrocene-1,1'-dicarbaldehyde, (II), to afford the title complex 3,3'-[(E,E)-ferrocene-1,1'-diyldimethylidyne]diindolin-2-one dichloromethane disolvate, [Fe(C(28)H(20)N(2)O(2))]·2CH(2)Cl(2), (IV). The structure of (IV) contains
