- <abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The first stereoselective syntheses of doubly linked (A‐type) oligocatechins, (+)‐procyanidin A<sub>2</sub> and (+)‐cinnamtannin B<sub>1</sub>, have been achieved. Ethylenedioxy‐bridged flavans served as excellent platforms, thus allowing annulation with nucleophilic catechin units in a stereoselective manner. An additional key was the new synthetic approach to selectively protected nucleophilic catechin, thus enabling regioselective construction of the key dioxabicyclo skeleton of the A‐type oligocatechins.</p> </abstract>
