  Semi-synthesis of A.23187 (calcimycin) analogs with 5-n-amino substituents. Their complexation of calcium and magnesium

  摘要：

  The semi-synthesis of A.23187 (calcimycin) analogs 1-4 bearing the respective substituents: 5-NH2, 5-NHCH3, 5-N(CH3)2, 5-NHCOCH3 was carried out. The complexing properties of 1-4 for calcium and magnesium were determined by two-phase experiments (water/toluene-butanol 70:30 W/W) and found to be much weaker than these of A.23187 or X.14885A. There was a discrepancy with theoretical predictions made from model carboxybenzoxazoles.
