Article abstract of DOI:10.1246/cl.1999.889

Intramolecular asymmetric lactonizations of two cyclic hydroxydiamides bearing (R,R)-1,2-diphenylethylenediamine as a chiral auxiliary were performed by the use of trifluoroacetic acid as an acid catalyst.The reactions proceeded smoothly at r.t. affording
