The combination of great effectiveness and ready availability should make the new phthalazine cinchona derivatives 1 and 2 the AD'S workhorse ligands for some time to come. Nevertheless, terminal olefins are the most common and important members of the olefin family and since most representatives are still below the 90% ee level (Table I, entries 7-12), the search for new ligands con- tinues. ...
