The author regrets that two appropriate references were not
cited in their paper. They should be included as follows.
In the Introduction the sentence:
Recently, we reported total synthesis of (±)-sacidumlignan D using Ueno–Stork radical cyclization as a
key step for the biomimetic construction of the C8–C8′ bond (Scheme 1a),4 and
plausible biogenetic conversion of this rearranged tetrahydrofuran
lignan to sacidumlignan A
with a 7′-arylnaphthalene backbone.
Should be changed to:
In connection with the first total synthesis of (±)-sacidumlignan D by Ramana;4a recently, we also reported its synthesis using Ueno–Stork
radical cyclization as a key step for the biomimetic construction of the
C8–C8′ bond (Scheme 1a),4b
and plausible biogenetic conversion of this rearranged tetrahydrofuran
lignan to sacidumlignan A
with a 7′-arylnaphthalene backbone.
