Eco-friendly K-10 Clay-Mediated [3 + 3] Spiroannulation of Morita-Baylis-Hillman Adduct of Isatin with Anthracene: Synthesis of Green Fluorophore Compounds.


ABSTRACT: An easy and simple spiroannulation of the Morita-Baylis-Hillman adduct of isatin derivatives with anthracene was achieved in moderate-to-good yields (37-75%). The spiroderivatives synthesized in this work exhibited green fluorescence properties. The reaction occurred in metal-free eco-friendly K-10 clay-mediated conditions. The final products have multiple structural features such as 3-spirooxindole, fluorophoric anthracene, phenanthracene, phenalene, and perylene cores.
