Design and synthesis of ninhydrin-based cyclophanes as potential neutral receptors for quaternary ammonium cations
Na, Jeong Eun,Lee, Shim Sung,Kim, Jae Nyoung
, p. 7435 - 7440 (2004)
Four ninhydrin-based cyclophanes 4a, 4b, 6a, and 6b were designed and synthesized. Two rectangular type cyclophanes (4a and 4b) and two square type cyclophanes (6a and 6b) were prepared in 8-43% yields.
