Fragmentation of carbonyl oxides by N-oxides: an improved approach to alkene ozonolysis.
[Structure: see text] Ozonolysis of alkenes in the presence of amine N-oxides results in the direct formation of aldehydes. This reaction, which appears to involve an unprecedented trapping and… Expand
'Reductive ozonolysis' via a new fragmentation of carbonyl oxides
Abstract This account describes the development of methodologies for ‘reductive’ ozonolysis, the direct ozonolytic conversion of alkenes into carbonyl groups without the intermediacy of… Expand
Asymmetric Synthesis of 1,2-dioxanes: Approaches to the Peroxyplakoric Acids.
The stereospecific intramolecular alkylation of a hydroperoxyacetal provides the basis for the first asymmetric synthesis of the dioxane propionate core of the peroxyplakorates. Chemoselective… Expand
Rational design of a rapid fluorescent approach for detection of inorganic fluoride in MeCN–H2O: a new fluorescence switch based on N-aryl-1,8-naphthalimide
A fluoride chemosensor (FCS-1) based on 1,8-naphthalimide bearing a trimethylsilyl ether has been designed and synthesized. FCS-1 displayed high selectivity and sensitivity to fluoride in inorganic… Expand

Efficient synthesis and conformational investigations of cis-pentacenediols
Diisobutylaluminum hydride is utilized to reduce pentacene-6,13-diones to the corresponding diols, useful precursors to functionalized pentacenes. This pathway is mild and efficient, and produces the… Expand
Gem-dihydroperoxides (g-DHPs), often referred to as 1,1-dihydroperoxides, are a class of molecules of interest because of their reactivity as well as their utility as synthetic reagents and… Expand
