The convenient preparation of chiral tetrahydrothiophenes (THTs) in high enantiopurity via phosphorothioic acids and relatedcompounds is reported. We consider these to be safer alternatives to the use of H(2)S which is a highly toxic gas. Each of the THTs is derivedfrom a common intermediate, thereby greatly enhancing the flexibility of the synthesis. The key transformation is a base-promoted, intramolecular

The preparation and base solvolyses of some S-phosphorylated derivatives of 2-mercaptoethanol and related compounds are reported. The fully esterified derivatives possessing favourable stereochemistryrearrange to the O-phosphorylated derivatives which then undergo elimination of an episulphide. In contrast, the mono-esterified derivatives eliminate alkoxide to give the cyclic intermediate [graphic

An efficient synthesis of the electrophilic reagent, -(1,3-dioxoisoindolin-2-yl)‑diethyl phosphorothioate (SDDP) is described. Moreover, the synthetic applications of SDDP wherein the transfer of the SP(O)(OEt) moiety occurs were investigated. In this manner, SDDP underwent facile SP(O)(OEt) transfer with electron-rich substrates such as ketones, indoles, and thiols to form -phosphorothiolated ketones
