<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The asymmetric addition of N‐Boc‐imines (II) to 3‐substituted oxindoles (I) leads to chiral 3, 3‐disubstituted oxindoles with 86‐96% diastereoselectivity (the main diastereomer is readily isolated by a column chromatography).</p> </abstract>
