The reaction of substituted ethylenediamines with various fumarates, maleates, and maleimides to form substituted ketopiperazine aceticacidesters and amides was investigated. This method affords a straightforward, high yield approach to a variety of potential peptidomimetics and can yield surprising results with regard to regio- and stereoselectivity.
