Description General description Isatin undergoes Pd(II)-catalyzed C-H addition by direct sp2/sp3 C-H bond activation to form 3-substituted-3-hydroxy-2-oxindoles. Isatin derivatives (bis-Schiff base) are synthesized by the condensation of the natural or synthetic isatins with hydrazine. Application Isatin is used as a reference material in the preparation of indigo and Maya Blue. It is also responsible for the yellow color exhibited by the “Maya Yellow” pigment. Reactant for preparation of: • Phthalazinone derivatives • Spirooxindole derivatives • Agents against multidrug-resistant cells expressing P-glycoprotein • Thiazolidinones spiro-fused to indolin-2-ones as potent and selective inhibitors of Mycobacterium tuberculosis protein tyrosine phosphatase B • Triazole-isatine compounds as potential antibacterial and antifungal agents • Biologically relevant scaffolds such as spiro[indole-thiazolidinones] Reactant for: • Cascade reactions with heterocyclic ketene aminals • Knoevenagel condensation reactions Packaging 5, 100, 500 g in poly bottle
