strong N-substituent effect is observed in the reaction of isoindoles with cyclobutene-1,2-diesters: N-alkyloxycarbonyl derivatives react to form adducts with bent-frame stereostructures; N-alkylisoindoles produce both extended-frame (stable) and bent-frame (unstable) stereoisomers, but require high-pressure conditions (10–15 kbar); N-acyl isoindoles fail to react.
