Pages 182 and 185: The name of the lichen ClaVaroids sp. from which the fungus was isolated should be corrected as MulticlaVula sp. The authors apologize for any inconvenience caused by this error. NP900197P 10.1021/np900197p Published on Web 04/17/2009
Figure 1. Chem3D minimized model of (+)-dihydrodiscorhabdin A (3). Page 461: The published Chem3D energy-minimized structure (Figure 1) needs to be corrected, and the C-3 configuration in (+)dihydrodiscorhabdin A (3) revised as shown. The revised (global) energy-minimized representation of 3 (revised Figure 1) provides dihedral angles that support calculated coupling constants [(expt J3,4a 2.8 Hz and J3,4b 2.8 Hz, calcd J3,4a (55°) 2.5 Hz and J3,4b (62°) 1.6 Hz)] that define the relative configuration about C-3 in 3 as indicated. The authors apologize for any inconvenience. NP9003596 10.1021/np9003596 Published on Web 06/19/2009
