Photochemical Deracemization of 3‐Substituted Oxindoles [PDF]
AbstractRacemic 3‐substituted oxindoles were successfully converted into enantiomerically pure or enriched material (up to 99 % ee) upon irradiation at λ=366 nm in the presence of a chiral benzophenone catalyst (10 mol %). The photochemical deracemization process allows predictable editing of the stereogenic center at carbon atom C3.

Oxindole–benzothiazole hybrids as CDK2 inhibitors and anticancer agents: design, synthesis and biological evaluation [PDF]
In the current study, molecular hybridization between the oxindole core and benzothiazole system through an acetohydrazide moiety was accomplished for the design of a new series of oxindole–benzothiazole hybrids 9a–r targeting CDK2 for cancer therapy ...

Solvent controlled synthesis of spiro and nonspiro indolinones with aminonaphthoquinone and pyrazolone moieties [PDF]
This study describes the design and synthesis of novel hybrid molecular architectures based on the privileged indolin-2-one (oxindole) scaffold. The research leverages a multi-component reaction strategy, employing isatins, 2-amino-1,4-naphthoquinone ...
