Treatment of highly decorated bicyclo[2.2.1]heptadienes with the protic ionic liquid, TfOH:TEA effected quantitative conversion to the corresponding N-substituted 5-hydroxy-4-methyl-3-oxoisoindoline-1-carboxamides. This approach provides rapid access important chemical space for the rapid development of highly functionalised oxoisoindoline and is highly substrate tolerant.
