    • Regarding the NOE correlations observed with natural celogentin C, the text of ref 1 is in error. The correct data can be located in Table 3 and on the NOESY spectrum given in the Supporting Information. This discrepancy caused us previously to erroneously conclude that our model right-hand ring of celogentin C was the unnatural atropisomer see ref 13
