Indium(Iii)-Catalyzed Reductive One-Pot Synthesis of Thioethers from Aromatic Aldehydes and Elemental Sulfur
摘要:
Described herein is that a combination of InI3 and 1,1,3,3-tetramethyldisiloxane (TMDS) effectively promotes the reductive thioetherification from aromatic aldehydes with elemental sulfur (S-8).

Pre-treatment with &agr;,&bgr; unsaturated aryl sulfones protects normal cells from the cytotoxic side effects of two classes of anticancer chemotherapeutics. Administration of a cytoprotective sulfone compound to a patient prior to anticancer chemotherapy with a mitotic phase cell cycle inhibitor or topoisomerase inhibitor reduces or eliminates the cytotoxic side effects of the anticancer agent on normal cells. The cytoprotective effect of the &agr;,&bgr; unsaturated aryl sulfone allows the clinician to safely increasing the dosage of the anticancer chemotherapeutic.

The present invention provides novel sulfoximine compounds, compositions comprising these compounds and methods of using these compounds as inhibitors of CYP24. In particular, the compounds of the invention are useful for treating diseases which benefit from a modulation of the levels of 1α,25-dihydroxy vitamin D3, for example, cell-proliferative disorders.
Indium-catalyzed Direct Conversion of Dibenzyl Ethers to Dibenzyl Sulfides Using Elemental Sulfur and a Hydrosilane and Its Application to the Preparation of Benzyl Selenides
compound, a hydrosilane and an easily handled form of elemental sulfur (S8) that effectively and directly catalyzes the sulfidation of dibenzyl ethers to produce dibenzyl sulfides. This system could also be applied to selenium in a straightforward conversion to dibenzyl selenides.
Indium-catalyzed direct preparation of dibenzyl sulfides from benzyl alcohols and elemental sulfur with a hydrosilane and its application to the preparation of dibenzyl selenide
system composed of InI3 and a hydrosilane efficiently and directly introduce elemental sulfur into the structure of dibenzyl sulfides via a nucleophilic substitution of benzyl alcohols. Also, we describe the application of this reducing system in the direct preparation of a dibenzyl selenide derivative with selenium.
