Straightforward Synthesis of Enantiopure 2,3-Dihydro-
benzofurans by a Sequential Stereoselective Biotransforma-
tion and Chemical Intramolecular Cyclization
Several stereochemical configurations are incorrect in the
Graphical Abstract and Schemes 3 and 4. Corrections
are shown in blue.
In the Graphical Abstract, the stereochemistry of the
benzofuran derivative chiral center should be as follows.
In Scheme 3, previous (()-3e should be (R)-3e and the
stereochemistry of the benzofuran derivative (R)-4 chiral
center should be as follows.
Scheme 3

Scheme 4
In Scheme 4, the stereochemistry of alcohols (S)-7 and
9À12 and benzofuran derivatives (R)-4 and 13À16 were
wrong and have been corrected.
Page 3501, bottom left column. Replace “benzofuran (S)-
16.” with “benzofuran (R)-16.” in this sentence: “It must
be mentioned that at higher palladium loading the hydro-
genation of the benzofusionated phenyl ring of (S)-2h
was observed, leading to the formation of diol (S)-12,
an adequate precursor for the synthesis of benzofuran
(R)-16.”
