substituent could be used to predictably modulate the reactivity of the resulting CC-1065/duocarmycin alkylation subunit analogue is detailed and its extension to a unique series of N-alkenyl derivatives is reported. The N-aryl derivatives were found to be exceptionally stable and to exhibit well-defined relationshipsbetweenstructure (X-ray), reactivity, and cytotoxic potency. When combined with the results
