Due to the particularity of the thiocarbonyl group (C S bond), only limited C(sp3)-H thiocarbonylation methods, especially efficient and convenient methods, have been developed for the synthesis of thioamides. Inspired by the “solvent-specifici

We report herein a protocol for thiolactam preparation with potassium sulfide via visible-light-mediated C(sp3)–H thiocarbonylation, in which polysulfide dianions and radical anions generated from potassium sulfide were the key active species. A variety of thiolactams were straightforward established under mild conditions. Moreover, it was successfully applied to structural modification of tetrahydroberberine.

3-Hydroxyisoindolinones (ring form) as well as their chain tautomers, o-acylbenzamides, were prepared from the reactions of 3-benzalphthalide 1, 3-halophthalides 3, and o-acylbenzoic acids 6 or their esters 7 with amines 2, and those of phthalimides 4 wit
Photoreactions of Isoindoline-1-thiones with Alkenes: Unusual Formation of Tricyclic Isoindolines
Nishio, Takehiko,Okuda, Norikazu
, p. 4000 - 4005 (2007/10/02)
Photochemical cycloaddition reactions of cyclic thioamides and alkenes have been examined.Irradiation of 2-arylisoindoline-1-thiones 1 in the presence of alkenes 2 gave the unexpected tricyclic isoindolines 3-18.The formation of tricyclic isoindolines can
