The reductive intermolecular coupling of phthalimides with esters by low-valenttitanium gave five-, six-, and seven-membered cyclized products as α-hydroxyketones and their further reduced ketones. The obtained cyclized products were transformed to alkylideneisoindolin-1-ones. The reductive intermolecular coupling of phthalimides with ketones by low-valenttitanium also gave five-, six-, and seven-membered
