Application
3H-1,2-Benzodithiol-3-one (1,2-benzodithiol-3-one) may be used as sulfur-transferring agent for the transformation of H-phosphonothioate and H-phosphonate diesters into the corresponding phosphorodi- and phosphoromonothioates.
3H-1,2-Benzodithiol-3-one may be employed as sulfurizing reagent in the preparation of phosphorothioate-containing oligodeoxyribonucleotides.
General description
3H-1,2-Benzodithiol-3-one is a heterocyclic building block.
3H-1,2-Benzodithiol-3-one is reported to react with triphenylphosphine to afford dithiosalicylide.

Previous methods for the preparation of phosphorothioate-containing oligodeoxyribonucleotides rely on the reaction of phosphite triesters with sulfurizing reagents such as tetraethylthiuram disulfide (TETD) and 3H-1,2-benzodithiol-3-one 1,1-dioxide (Beaucage reagent). However, these and other sulfurizing reagents suffer from several disadvantages, and there

Though less potent than the parent natural product leinamycin, S-deoxyleinamycin displays activity against human cancer cell lines that is comparable to many clinically used agents. The results reported here suggest that the 1,2-dithiolan-3-one heterocycle found in S-deoxyleinamycin reacts with thiols
