  Synthesis, Characterization, and Alkali Metal Stability Constants of a New Bis(phosphotriester) Macrobicyclic Polyether Cryptand

  摘要：

  The synthesis of a new bis(phosphotriester) macrobicyclic polyether cryptand, O=P[O(CH2)(2)O(CH2)(2)O(CH2)(2)O]P-3=O (9), called phosphocrypt, and its acyclic tripodal precursor O=P[O(CH2)(2)O(CH2)(2)O(CH2)(2)OH](3) (8) are described. The new cryptand 9 was synthesized by condensation of 8 and phosphoryl chloride which were simultaneously added under high dilution conditions in the presence of pyridine. The highest yield of 9 (30%) was obtained with a final concentration of 3 mM in vigorously stirred methylene chloride. Both 8 and 9 form stable complexes with K+ and Rb+ in water. Log K-s values measured with a cation selective electrode for 8 are 3.6 and 3.0 and 3.7 and 3.6 for 9, respectively. The K-s values for phosphocrypt are 1000-fold greater than those of comparably sized nitrogen bridgehead cryptands. H-1 and C-13 NMR indicate 9 is flexible at 20 degrees C. Molecular dynamics and mechanics calculations indicate that phosphocrypt has more cation-dipole interactions and more favorable conformational changes associated with complexation than comparably sized nitrogen bridgehead cryptands.
