The absolute configuration of 5a was determined by the comparison of HPLC retention time: P. Herold, A. F. Indolese, M. Studer, H. P. Jalett, U. Siegrist, H. U. Blaser, Tetrahedron 2000, 56, 6497; the absolute configuration of 5f was also determined by the Mosher esterification method (see Supporting Information).
