Dipolar cycloaddition of carbonyl ylides to 2-oxoindolinylidenes: a facile approach towards the synthesis of functionalized spiroindolenins

Oxoindolinylidenes undergo regiospecific dipolar cycloaddition with carbonyl ylides affording highly functionalized spiroindolenin systems in high yield. Graphic
