WebNov 23, 2006 · Abstract The novel thiacalix [4]-1,3-2,4-aza-biscrown 3 in 1,3-alternate conformation, was facilely prepared by “1 + 2” cyclocondensation of p-tert -butylthiacalix [4]arene tetrahydrazide derivative 2 with o -phthalaldehyde in yield of 78%. WebJan 17, 2011 · Inherently chiral calixarenes, whose chirality is based on the absence of a planar symmetry or an inversion center in the molecules as a whole through the asymmetric array of several achiral groups upon the three-dimensional calix-skeletons, are challenging and attractive chiral molecules, because of their potential in supramolecular chemistry. …

WebThe concept of bisthioxanthylidene biscrown ethers as potential stereodivergent chiral ligands in asymmetric synthesis is introduced. Substituted bisthioxanthylidenes may be chiral and can exist as stable enantiomers due to their folded structure.
