Three representative BINOLderivatives were examined for their chiralrecognitions with d- and l-t-Boc-amino acid anions: an open system 1, which bears two urea groups and two pyrene groups; a closed ring system 2, which bears two urea groups with a closed ring system; and a dimeric system 3, which bears two benzylic amine groups and two pyrene groups. Dimeric system 3 displayed a ΔID/ΔIL of 12.95
研究了三种代表性的BINOL衍生物与d-和l - t -Boc氨基酸阴离子的手性识别:一个开放系统1,带有两个脲基和两个pyr基;闭环系统2,其具有带有闭环系统的两个尿素基团;二聚体系3,其带有两个苄基胺基和两个pyr基。二聚体系统3中显示的Δ我d /Δ我大号12.95为吨-Boc-丙氨酸。
