Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The combination of palladium(II) acetate/(<italic>R</italic>)‐xylyl‐Phanephos and silver triflate (Pd:Ag=1:1) was found to be an efficient catalytic system for the asymmetric ring opening reactions of oxabenzonorbornadienes with terminal alkynes. The products were typically afforded in good yields (up to 95% yield) and with high enantioselectivities (up to 99% <italic>ee</italic>).</p> <p> <boxed-text content-type="graphic" position="anchor" orientation="portrait"> <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1fbrpcqh" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /> </boxed-text> </p> </abstract>
