A series of cis-2,6-tetrahydropyran-4-ones was synthesized from the intramolecular cyclization reaction of β-hydroxy allyl ketones in the presence of Me3SiOTf as catalyst. The β-hydroxy allyl ketone was prepared from allylation reaction with β-hydroxynitrile without protection of hydroxy functionality under the Barbier-type reaction condition.

A tandem double Friedel-Crafts reaction of indoles and nonsymmetrical divinyl ketones has been achieved. The tandem reaction forms complex [6-5-7]-tricyclic indoles in excellent yields. The reaction is completely regioselective and offers high levels of s
Asymmetric Ni-catalyzed conjugate allylation of activated enones
Sieber, Joshua D.,Morken, James P.
, p. 4978 - 4983 (2008/09/20)
The nickel-catalyzed enantioselective addition of allylboronic acid pinacol ester, allylB(pin), is described. This reaction is highly effective with dialkylidene ketones and favors the allylation of the benzylidene site in nonsymmetric substrates. The rea
