Synthesis of Deuterated (E)-Alkene through Xanthate-Mediated Hydrogen-Deuterium Exchange Reactions

Herein we have developed a reversible hydrogen-deuterium exchange reaction of nonactivated olefins. By using EtOCS2K as a mediator, the H/D exchange reaction was realized through repeated addition and elimination reactions, demonstrating reversible H/D exchange between ordinary olefins and deuterated olefins. Using the lowest cost D2O without precious metal catalysts and ligands, a broad spectrum of compatibility of functional groups was achieved.

Convenient synthesis of 1,3-dithiolane-2-thiones: Cyclic trithiocarbonates as conformational locks

A series of novel 1,3-dithiolane-2-thiones, or cyclic trithiocarbonates, has been prepared by a new simple procedure: a treatment of the corresponding epoxides with the commercially available potassium ethyl xanthogenate, KSC(S)OEt. The stereochemistry of the products was determined by 1H NMR and in some cases by single-crystal X-ray data. Cyclohexane-based 1,3- dithiolane-2-thiones revealed a trans-fusion of the carbo- and hetero-cycles. The products obtained from the mono-substituted cyclohexene oxides demonstrated an axial position of the substituents. Thus the epoxide transformation into trithiocarbonate can be used as a method for locking cyclic compounds in unstable conformations.ARKAT-USA, Inc.

Zeolite molecular sieve 4: A reusable catalyst for fast and efficient conversion of epoxides to thiiranes with thiourea

Various epoxides are readily converted to their corresponding thiiranes by thiourea/zeolite molecular sieve 4 system in refluxing MeOH. All reactions were carried out within 12-25 min to give thiiranes in 80%-99% yields. The catalyst saves its catalytic activity for several times at this transformation. Stereospecific conversion of (R)-(+)-styrene oxide to (S)-(+)-styrene episulfide was achieved by this combination system. Taylor & Francis Group, LLC.
