DOI: 10.1016/j.tet.2020.131725
Abstract: ABSTRACT The reductive intermolecular coupling of phthalimides with esters by low-valent titanium 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… read more here.
