Imazaki, Yusuke,Shirakawa, Eiji,Hayashi, Tamio
experimental part, p. 10212 - 10215 (2012/01/05)
A ruthenium complex coordinated with 3,4,7,8-tetramethyl-1,10- phenanthroline catalyzed the reaction of alkenyl triflates with zinc dithiolates to give alkenyl sulfides.
Thiolysis of 1,2-epoxides by thiophenol catalyzed under solvent-free conditions
Fringuelli, Francesco,Pizzo, Ferdinando,Tortoioli, Simone,Vaccaro, Luigi
, p. 6785 - 6787 (2007/10/03)
Thiolysis of alkyl- and aryl-1,2-epoxides was investigated under solvent-free conditions in the presence of Lewis and Br?nsted acid and base catalysts (InCl3, p-TsOH, n-Bu3P, K2CO3). Five mol% of catalyst was su
Cyclization by intramolecular carbolithiation of alkyl- and vinyllithiums prepared by reductive lithiation: Surprising stereochemistry in the lithium oxyanion accelerated cyclization
Deng, Kai,Bensari, Ahlem,Cohen, Theodore
, p. 12106 - 12107 (2007/10/03)
The versatility of intramolecular carbolithiation of simple alkenes to yield cyclopentylmethyllithiums by unconjugated organolithiums is greatly increased (1) by generating the organolithiums by reductive lithiation of phenyl thioethers with aromatic radi
Synthesis of α-methylene-β-hydroperoxy sulfoxides by regioselective photooxygenation (Schenck Reaction) of racemic vinyl sulfoxides
Adam,Kumar,Saha-Moller
, p. 1525 - 1528 (2007/10/02)
The β-hydroperoxy vinyl sulfoxides 3 were synthesized in good to excellent yields by regioselective photooxygenation of racemic vinyl sulfoxides 2. Moderate diastereoselectivities were observed in the ene reaction of singlet oxygen (Schenck Reaction) with

Cohen, Theodore,Doubleday, Mary Dosch
, p. 4784 - 4786 (2007/10/02)
Cyclohexenyl, cycloheptenyl, and cyclooctenyl phenyl sulfides, readily prepared from the corresponding cycloalkanones, are reductively lithiated by lithium p,p'-di-tert-butylbiphenylide to produce cycloalkenyllithiums in good yields.
Clay Catalysis: A Simple and Efficient Synthesis of Enolthioethers from Cyclic Ketones
Labiad, Bouchta,Villemin, Didier
, p. 143 - 144 (2007/10/02)
Montmorillonite KSF in refluxing toluene catalyses the synthesis of 1-alkyl- and 1-arylthioalkenes from ketones and thiols (thiophenol or 1-butanethiol).
ENOL THIOETHERS AS ENOL SUBSTITUTES. AN ALKYLATION SEQUENCE.
Trost,Lavoie
, p. 5075 - 5090 (2007/10/02)
Ionic bromination of enol phenyl thiolethers forms predominantly to exclusively 2-(phenylthio)-3-bromo-1-alkenes, an enolonium equivalent. The allylic bromide participates in displacements with stabilized and nonstabilized nucleophiles. The ability to hydrolyze the enol thioethers to their corresponding ketones equates this sequence to an equivalence of an enolonium ion. The versatility of the sulfur in selective introduction of allylic hydroxyl and amino groups as well as the ability to directly replace the sulfur substituent by hydrogen or alkyl imparts special significance to this approach. The sequence is highly regio-and chemoselective. Applications include the synthesis of lanceol and bisabolene and the introduction of steroid side chains.
