- Xanthates as Thiol Surrogates for Nucleophilic Substitution with Aryl Halides
-
We herein report an unprecedented xanthate-based protocol for the preparation of aryl-alkyl thioethers. Heating xanthates with aryl halides and namely cesium carbonate in methanol provides the target thioethers in generally good yields within short reaction times. This method allows one to avoid contact with odorous thiols and also to introduce substituents of which the corresponding thiols are virtually unavailable or inconvenient in use.

- Microwave-promoted "one-Pot" synthesis of 4- nitrobenzylthioinosine analogues using thiourea as a sulfur precursor
-
An efficient one-pot method for the synthesis of various C6-alkylthio-substituted purine nucleosides has been developed under microwave irradiation with good to excellent yields without any metal catalyst (see scheme). This process expands the scope of existing synthetic methodologies and was further successfully applied for synthesis of the biologically important compound 4-nitrobenzylthioinosine (NBTI).
