Aponick, Aaron; Li, Chuan-Ying; Palmes, Jean A. published the artcile< Au-Catalyzed cyclization of monopropargylic triols: an expedient synthesis of monounsaturated spiroketals>, Computed Properties of 617-55-0, the main research area is spiroketal derivative preparation; monopropargylic triol preparation cyclization gold; gold cyclization catalyst.
The gold-catalyzed cyclization of monopropargylic triols to form olefin-containing spiroketals is reported. The reactions are rapid and high yielding when 2 mol % of the catalyst generated in situ from Au[P(t-Bu)2(o-biphenyl)]Cl and AgOTf is employed in THF at 0 °C. A range of differentially substituted triols leading to substituted 5- and 6-membered ring spiroketals were prepared and function well in the reaction.
Organic Letters published new progress about Cyclization. 617-55-0 belongs to class esters-buliding-blocks, and the molecular formula is C6H10O5, Computed Properties of 617-55-0.
