Five novel 4-phenylquinazolinols were synthesised in three steps. Their application as ligands in the titanium tetraisopropoxide promoted catalytic enantioselective addition of phenylacetylene to a variety of aldehydes gave propargylic alcohols. Under the
Synthesis of phosphine-ligated zinc acetylide dimers: Enhanced reactivity in carbonyl additions
Wilson, Erin E.,Oliver, Allen G.,Hughes, Russell P.,Ashfeld, Brandon L.
experimental part, p. 5214 - 5221 (2011/11/13)
Phosphine-ligated dinuclear zinc acetylides effectively promote the alkynylation of carbonyl derivatives. Good to excellent yields (46-91%) of the corresponding propargylic alcohols were obtained from a wide range of substrates. Crystallographic evidence
Reactivity of 3-silyloxy-1,4-enynes: Gold(III)-catalyzed regioselective nucleophilic substitution
Haug, Timm T.,Harschneck, Tobias,Duschek, Alexander,Lee, Chang-Uk,Binder, J?rg T.,Menz, Helge,Kirsch, Stefan F.
experimental part, p. 510 - 514 (2009/06/05)
Gold-catalyzed reactions of 3-silyloxy-1,4-enynes with alcohols afford primary, secondary, and tertiary pent-2-en-4-ynyl ethers in moderate to excellent yields. The substitution proceeds with high regioselectivity. An initial cyclization providing five-me
