Silica-Supported Silver Nitrate as a Highly Active Dearomatizing Spirocyclization Catalyst: Synergistic Alkyne Activation by Silver Nanoparticles and Silica
Clarke, Aimee K.,James, Michael J.,O'Brien, Peter,Taylor, Richard J. K.,Unsworth, William P.
, p. 13798 - 13802 (2016)
Silica-supported AgNO3(AgNO3–SiO2) catalyzes the dearomatizing spirocyclization of alkyne-tethered aromatics far more effectively than the analogous unsupported reagent; in many cases, reactions which fail using unsupporte
Dearomatisation approaches to spirocyclic dienones via the electrophilic activation of alkynes
Clarke, Aimee K.,Liddon, John T. R.,Cuthbertson, James D.,Taylor, Richard J. K.,Unsworth, William P.
, p. 233 - 245 (2017)
Two complementary dearomatising spirocyclisation protocols to generate spirocyclic dienones from anisole and phenol-tethered ynones are described, each proceeding via electrophilic alkyne activation. The first approach focuses on the spirocyclisation of p
SYNTHESIS OF SUBSTITUTED SPIRODECA-3,6,9-TRIENE-2,8-DIONES: AN EXPEDITIOUS ROUTE TO THE SPIRODECANE TERPENE SKELETON
Haack, Richard A.,Beck, Kenneth R.
, p. 1605 - 1608 (2007/10/02)
Substituted spirodecanes are prepared in two steps in fair to moderate yield.A substituted 4-methoxyphenylacetyl chloride, prepared from the corresponding acid, is reacted with a substituted acetylene (or acetylene gas) in the presence of aluminium c
