Stereoselective Synthesis of Pyrans from Epoxyalkenes: Dual Catalysis with Palladium and Br?nsted Acid

We describe regio- and stereoselective cycloisomerizations of alcohols tethered to epoxyalkenes, to construct alkene-substituted pyrans. These transformations are best catalyzed by Pd(PPh3)4 in the presence of phosphite ligands, and with diphenylphosphinic acid as an essential Br?nsted acid cocatalyst for activation of the epoxyalkene.

Regiocontrol of the palladium-catalyzed tin hydride addition to Z-enynols: Remarkable Z-directing effects

(Figure Presented) Palladium-catalyzed hydrostannation of substituted Z- and E-enynols is discussed and compared. The regioselectivity of the H-Sn bond addition was found to be controlled by the geometry of the double bond (Z- or syn-directing effect) rather than the nature of its substituents, Exclusively α-vinyl stannanes were obtained from Z-enynols having various substituents on the double bond regardless of their electronic, steric, or chelating natures.
