In an article, author is Tay, Hui Min, once mentioned the application of 144163-85-9, Name is tert-Butyl ((2S,4S,5S)-5-amino-4-hydroxy-1,6-diphenylhexan-2-yl)carbamate, molecular formula is C23H32N2O3, molecular weight is 384.5118, MDL number is MFCD09833420, category is chiral-catalyst. Now introduce a scientific discovery about this category, Recommanded Product: 144163-85-9.
A semi-rigid chiral ligand (1R, 2R)-4,4′-(trans-cyclohexane-1,2-diyl)bis(azanediyl)bis(carbonyl) dibenzoic acid (H(2)cbba) was combined with various Co(II) salts and dipyridyl co-ligands to obtain four 2D homochiral coordination polymers of composition [Co(cbba)(dipyridyl)]center dot solvate (dipyridyl = 4,4′-bipyridyl (bipy), bis(4-pyridyl)ethylene (bpe), 1,4-bis(4-pyridyl)benzene (1,4-bpb), 2,5-bis(4-pyridyl)thiazolo [5,4-d]thiazole (2,5-bptztz)) (1-4). The topology of the frameworks is mediated by the length of the co-ligands, with short dipyridyl co-ligands (4,4′-bipy and bpe) resulting in the formation of (4(13).6(2)) networks (1-2), while long co-ligands (1,4-bpb and 2,5-bptztz) led instead to (4(4).6(2)) (sql) networks that undergo 2D -> 2D parallel interpenetration to form a rare example of a homochiral polyrotaxane (3-4). The length of the dipyridyl co-ligand was also found to have an effect on the conformation of the flexible cbba(2-) ligands and the crystal packing of the networks.
