corresponding N-substituted dimethyl 3-oxoisoindolin-1-ylphosphonates in good yield which, by means of a dephosphonylation reaction with lithiumaluminum hydride, give the target N-substituted isoindolin-1-ones in moderate to good yield. amino phosphonates - isoindolinones - C-P cleavage - microwave irradiation - one-pot reaction
reaction of aromatic aldehydes with N-(ω-hydroxyalkyl)-substituted 3-phosphoisoindolin-1-ones, obtained in one-pot synthesis from 2-formylbenzoic acid. Additionally, the intramolecular HWE reaction of the N-(ω-formylalkyl)-substituted phosphoisoindolin-1-ones afforded the corresponding isoindolone derivatives. Graphical Abstract
