In the polymerization of phenylalanine N-carboxyanhydride (NCA) in N02Ph initiated by MeNHBzl, L-, D-, and DL-NCAS were polymerized at the same rate, and no stereoselectivity was observed. When the same experiment was carried out in HCONEt2, however, L-and D-NCAS were both polymerized a t a rate whi
