Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A CC bond‐forming conjugate reaction was successfully applied to the enantioselective dearomatization of β‐naphthols. A C(sp2)C(sp3) bond is formed by using propargylic ketones as reactive partners. Good to excellent <italic>Z</italic>/<italic>E</italic> ratios and <italic>ee</italic> values were obtained by employing an in situ generated magnesium catalyst. Further transformations of the <italic>Z</italic>‐configured CC double bond in the products were achieved under mild reaction conditions. Moreover, the stereocontrolling element of this magnesium‐catalyzed dearomatization reaction was explored by computational chemistry.</p> </abstract>
