  The first example of γ-chloromagnesio γ-lactones: their generation from γ-tolylsulfinyl γ-lactones with isopropylmagnesium chloride, stability, and reaction with electrophiles

  摘要：

  The treatment of gamma-lactones having a sulfinyl group at the gamma-position, which were synthesized from I-chlorovinyl p-tolyl sulfoxides with lithium enolate of carboxylic esters, with isopropyl magnesium chloride in THF at -78 degrees C gave gamma-chloromagnesio gamma-lactones by the sulfoxide-magnesium exchange reaction in high yields. The generated gamma-chloromagnesio gamma-lactones were found to be stable at below -50 degrees C for at least 2 h. The reaction of these gamma-chloromagnesio gamma-lactones with electrophiles and the stereochemistry of the reactions were investigated. (c) 2006 Elsevier Ltd. All rights reserved.

• Remote participation during photooxidation at sulfur. Evidence for sulfurane intermediates

  The photooxidations of geminally substituted gamma-hydroxy sulfides results in formation of unusual oxidative elimination products. Detailed spectral data and the independent synthesis of a close analogue provide compelling evidence for the structures of these olefins. The formation of the olefins is attributed to decomposition of sulfurane intermediates. This conclusion is supported by a detailed kinetic study which separated the chemical, k(r), and physical, k(q), components to the overall deactivation of singlet oxygen. Those sulfides with the best geometry for sulfide-hydroxyl interaction are also the substrates which react most rapidly with singlet oxygen to give oxidation products. In addition, sulfone yields are in excess of 50% for the hydroxy-substituted sulfides but less than 5% for their hydrocarbon analogues. Several mechanisms that provide explanations for these unusually high sulfone yields are presented.
