Intramolecular hydrogen bond self-template synthesis of some new Robson-type macrocyclic ligands. Wu, Jin Cai; Tang, Ning; Liu, Wei Sheng; Tan, Min Yu; Chan, Albert S. C. (Department of Chemistry, Lanzhou University, Lanzhou 730000, Peop. Rep. China). Chinese Chemical Letters, 12(9), 757-760 (English) 2001 Chinese Chemical Society. CODEN: CCLEE7. ISSN: 1001-8417. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 28 The intramol. hydrogen bond self-template effect was suggested in the process of directly synthesizing the first six chiral metal-free Robson-type macrocyclic ligands. These ligands were characterized by 1H NMR, IR, FAB-MS. The macrocyclic compds. were prepd. by cyclocondensation 2-hydroxy-5-methyl-1,3-benzenedicarboxaldehyde, 5-chloro-2-hydroxy-1,3-benzenedicarboxaldehyde and 5-(1,1-dimethylethyl)-2-hydroxy-1,3-benzenedicarboxaldehyde with (1R,2R)-1,2-cyclohexanediamine or (1R,2R)-1,2-diphenyl-1,2-ethanediamine, resp. The Robson-type macrocyclic ligands included derivs. of (4aR,13aR,17aR,,26aR)-1,2,3,4,4a,13a,14,15,16,17,17a,26a-dodeca hydro-7,,24-dimethenodibenzo[b,m][1,4,12,15]tetraazacyclodoco sine-27,28-diol and (4R,5R,15R,16R)-4,5,15,16-tetraphenyl-3,6,14,17-tetraazatricyclo[17.3 .1.18,12]tetracosa-1(23),2,6,8,10,12(24),13,17,19,21-decaene-23,24-di ol. Manganese, cobalt, nickel and copper complexes of these ligands were prepd. and chem. yields were reported.
