Microwave-Assisted One-Pot [3+2] Cycloaddition of Azomethine Ylides and 3-Alkenyl Oxindoles: A Facile Approach to Pyrrolidine-Fused Bis-Spirooxindoles
Journal ArticleDOI
Organocatalytic [3 + 2] cycloaddition of oxindole-based azomethine ylides with 3-nitrochromenes: a facile approach to enantioenriched polycyclic spirooxindole-chromane adducts
TL;DR: An organocatalytic asymmetric [3 + 2] cycloaddition of oxindole-based azomethine ylides with 3-nitro-2H-chromenes has been developed, providing a facile approach to densely functionalized polycyclic spirooxindoles-chromane adducts featuring four contiguous stereogenic centers, including two tetrasubstituted carbon centers.
Journal ArticleDOI
Palladium-catalyzed cascade reactions of alkene-tethered carbamoyl chlorides with N-tosyl hydrazones: synthesis of alkene-functionalized oxindoles.
TL;DR: A palladium-catalyzed cascade reaction of alkene-tethered carbamoyl chlorides with N-tosyl hydrazones is described, which provided a new way to synthesize various alkenes-functionalized oxindoles bearing an all-carbon quaternary center.
Journal ArticleDOI
Diversity oriented synthesis of β-carbolinone and indolo-pyrazinone analogues based on an Ugi four component reaction and subsequent cyclisation of the resulting indole intermediate
TL;DR: In this article, a one-pot domino multicomponent reaction for the rapid, integrated and versatile synthesis of highly functionalized β-carbolinones (9a-9ab) and indolo-pyrazinones (10a-10ab) has been established.

Rhodium(II)-catalyzed direct sulfenylation of diazooxindoles with disulfides
TL;DR: The transformation is proposed to proceed through sulfur ylide formation followed by S–S bond cleavage and rearrangement, providing a rapid synthetic route to 3,3-dialkylthiooxindoles, or 3, 3-diarylthiaxindoles in moderate to good yield.
