Abstract

Isoindolinones were constructed according to an original [4+2]-cycloaddition strategy. Unprecedented 5-amino-2-furyl­methylamines were prepared and revealed as efficient precursors of new aminoisoindolinones, obtained via a Diels-Alder and lactamization sequence.

A sequence involving the reaction between 1 and 2 prior to the successive addition of NaBH4 and then 5 was first envisaged, but did not succeed; the sequence between 1 and 2, then 5, prior to the addition of NaBH4 gave a mixture of products.
