Bi(OTf)3-catalyzed Meyer-Schuster rearrangement of electron-rich propargyl alcohols, followed by 1,4-addition of the resulting vinyl ketone, proceeded smoothly though Meyer-Schuster rearrangement of primary propargyl alcohols is rare. This tandem reaction can be extended to an intramolecular version, featuring a one-pot dihydroquinolone synthesis. (Chemical Equation Presented).
Unveiling the reactivity of propargylic hydroperoxides under gold catalysis
Alcaide, Benito,Almendros, Pedro,Quiros, M. Teresa,Lopez, Ramon,Menendez, Maria I.,Sochacka-Cwikla, Aleksandra

Controlled gold-catalyzed reactions of primary and secondary propargylic hydroperoxides with a variety of nucleophiles including alcohols, phenols, 2-hydroxynaphthalene-1,4-dione, and indoles allow the direct and efficient synthesis of β-functionalized ke
Highly efficient p-toluenesulfonic acid-catalyzed alcohol addition or hydration of unsymmetrical arylalkynes
Olivi, Nathana?l,Thomas, Emmanuel,Peyrat, Jean-Fran?ois,Alami, Mouad,Brion, Jean-Daniel

Under a catalytic amount of PTSA in aqueous or alcoholic media, activated unsymmetrical arylalkynes 1 undergo regioselective water or alcohol addition to afford successfully carbonyl compounds 2 in good to excellent yields. This new environmentally metal-free procedure, which afforded only Markovnikov adducts, is characterized by the mildness of acidic conditions and the excellent regio- and chemoselectivity.
