Additions and Corrections Pro-D-NMe-Amino Acid and D-Pro-NMe-Amino Acid: Simple, Efficient Reverse-Turn Constraints [J. Am. Chem. Soc. 1995, 117, 5927-5937]. DAVID K. CHALMERS AND GARLAND R. MARSHALL* Page 5931: The definition of the virtual torsion angle  as shown in Figure 2 (CR1, CR2, CR3 N4) does not match that of Ball et al. (refs 14 and 74: carbonyl carbon 1, CR2, CR3, N4). Using the corrected definition of  has little effect on Figure 5 and does not alter the conclusions of the paper. Figure 5B calculated using the corrected definition of  is given in the supporting information. Figure 5B calculated using the corrected definition of  (1 page).
