Abstract
As is known, 3-acylrnethylene-2-indolones may serve as initial compounds for obtaining various 3-spiro derivatives of hydroxyindole by the Diels-Alder reaction with alkadienes [I, 2]. Analogous compounds with close structures-3-spiroindolones-are formed by the Michael reaction of 3-acylmethylene-2-indolones with various CH-activated carbonyl compounds [3, 4] and enamines [5], and by condensation with binucleophiles such as thiourea, ...
