Characterization of chiral host-guest complexation in fast atom bombardment mass spectrometry

A new method has been developed for the characterization of complexion between host and guest molecules. Adduct formation between chiral crown ethers 1 and 2 and enantiomeric ammonium ions 4 and 5 was examined. The reference compound 3 (achiral host) was chosen to be similar in structure to the chiral crown ethers for quantitative measurements. Our approach is based on a formalism assuming an equilibrium: [chiral host + H]+ + [achiral host + chiral guest]+1 [chiral host + chiral guest]+ + [achiral host + H]+. The equlibrium constant for this process was calculated using the relative peak intensities of the corresponding species in the FAB mass spectra. It was found that these provide significantly better reproducibility and more reliable results than the relative peak intensity method described before (Sawada, M.; et al. J. Am. Chem. Soc. 1992, 114, 4405; 1993, 115, 7381; Org. Mass Spectrom. 1993, 28, 1525).1-3 In the examples studied, the equilibrium constants corresponding to the formation of heterochiral adducts (S,S-R or R,R-S) were higher than those for the formation of homochiral aggregates (S,S-S or R,R-R).

The Preparation of Macrocyclic Polyether-Diester Compounds by Transesterification Including The Preparation of Two New Nitrogen Containing Diester-Crown Compounds

Macrocyclic polyether-diester compounds have been prepared by reacting oligoethylene glycols with the appropriate dimethyl esters in the presence of catalytic amounts of alkali metal methoxides.The methanol by-product was removed by molecular sieves.Product yields were improved for the preparation of all macrocyclic compounds except a compound containing a furan subcyclic group (4).Six new macrocyclic diester compounds (7-12) could only be prepared using the base catalyzed transesterification process since the acid chloride synthetic method failed or the acid chloride could not be made.The formation of compounds 5 and 6 from dimethyl 2,6-pyridine dicarboxylate (17) and the triethylene and tetraethylene glycols proceeded by way of half-transesterified intermediates.These intermediates were also observed for the base catalyzed decomposition of 5 and 6 in methanol to form the glycol and the diester 17.
