چکیده
The authors wish to inform readers that there is an error in the chemical structures shown in Figure 4 of this paper [1]. The structure shown in the bottom left corner is an extremely unlikely type of radical. Following the proposed route, it should yield an ortho-quinone (without the unpaired electron) and a pyranosyl sugar free radical. The ortho-quinone should then undergo nucleophilic attack by MeOH to form the product. The corrected Figure 4 is shown below.
