Additions and Corrections Vol. 54, 1989 S. D. Kahn, P. M. Booth, J. P. Waltho, and D. H. Williams*. Computer-Assisted Structure Determination. Structure of the Peptide Moroidin from Laportea moroides

Page 1901. The structure 1a in this paper correctly describes the deduced structure of moroidin. However, in the text, the stereochemistry at the β-carbon of the β-substitututed leucine residue of 1a (and of 1b, 1c, and 1d) is incorrectly described as S, due to an inadvertent error in application of the R/S convention. The stereochemistry at this center is R, as shown in structure 1a. JO004021N 10.1021/jo004021n Published on Web 11/08/2000

Page 7544. Compounds 12 and 14 in Table 1 were derived from maltose and maltotriose, respectively. The O-glycosidic linkages should have been drawn with R configurations rather than β configurations. The Nglycosidic linkage is correctly drawn as β. JO004036L 10.1021/jo004036l Published on Web 11/05/2000
