Ben derivatives have been prepared in five steps from 4-hydroxyproline by Barton cyanoethylation, ring closure, and derivitization. Proof of absolute configuration and practical synthesis of pure Ben enantiomers are described. In the accompanying communication we note that E-enaminonitriles can mim
