The authors note, on page 8243, right column, first paragraph, line 9, “The C7 atom of the hydrazone backbone is an isosteric center that adopts the transisomer configuration (Fig. 2C)” should instead read, “The C7 atom of the hydrazone backbone is an isosteric center that adopts the Z-isomer configuration (Fig. 2C).”
