P(RNCH2CH2)3N-catalyzed 1,2-addition reactions of activated allylic synthons
Kisanga, Philip B.,Verkade, John G.
, p. 426 - 430 (2007/10/03)
Activated allylic compounds of the type RCH:CHCH2Z (Z = CN, CO2Me) react efficiently with aromatic aldehydes in the presence of 20-40 mol % of P(R′NCH2CH2)3N at -94 to -63 °C. Both R = H and R = Me le
Catalytic asymmetric access to α,β unsaturated δ-lactones through a vinylogous aldol reaction: Application to the total synthesis of the Prelog-Djerassi lactone
Bluet, Guillaume,Bazan-Tejeda, Belen,Campagne, Jean-Marc
, p. 3807 - 3810 (2007/10/03)
Figure presented A one-step catalytic asymmetric access to α,β unsaturated δ-lactones is described, using a vinylogous Mukaiyama-aldol reaction between a γ-substituted dienolate and various aldehydes in the presence of Carreira catalyst CuF·(S)-tolBinap.
Reactions of α-or χ-Phenylthio Substituted Extended Enolate Anions Derived from Esters
Brownbridge, Peter,Durman, John,Hunt, Paul G.,Warren, Stuart
, p. 1947 - 1958 (2007/10/02)
The title anions are alkylated and acylated (α series only) exclusively at the α position.The α-phenylthio products give χ-phenylthio compounds by the PhS shift and the PhS group may be removed from the products in a number of ways.
ACYLATION OF EXTENDED ENOLATE IONS FROM α-PHENYLTHIO(PhS-)CROTONATE ESTERS
Durman, John,Warren, Stuart
, p. 2895 - 2898 (2007/10/02)
C-Acylation, like alkylation, occurs at the α-position of title compounds to give unsaturated keto-esters from which the PhS group may be removed.
