The title compound is an enynoate bearing a protected amino group at the olefinic C atom next to the ester group. The amino group is protected with a benzyl and a benzyloxycarbonyl group. The compound belongs to the group of acetylenic Michael acceptors which react with organocuprate reagents in a 1,6-Michael addition to functionalized allenes. Bearing a protected amino group, the title compound could be a precursor in the synthesis of allenic [alpha]-amino acids.
