In order to overcome this oxidation problem the synthesis of 21 and 22 was achieved in which two methyl groups occupy the positions bridging the two pyrrolic groups (Figure 20).16 Although compounds 21 and 22 were found to be stable, less stable complexes with anions were formed than with the first generation dipyrrolylmethane systems. However, despite this reduction in affinity, the stability constants for these receptors could only be calculated in DMSO-c/6/5% H20 for fluoride (124 and 89 M 1), dihydrogen phosphate (1092 and 81 M"1), benzoate (1092 and 81 M"1) calculated for receptors 21 and 22 respectively.

To 5.69 g of this acetal in 410 ml of t-butanol and 11 ml of water was added a mixture of 5.80 g of potassium carbonate, 22,8 g of sodium periodate, and 270 mg of potassium permanganate in 1230 ml of water. The reaction mixture was stirred at 20-25°C for 20 hours and concentrated in vacuo to remove t-butanol. Ethylene glycole (0.5 ml) was added and reaction mixture extracted with 1 1 ether-benzene to remove neutral material. The aqueous layer acidified with solid sodium dihydrogen phosphate and extracted 4 times with 1 1 ethyl acetate-benzene. The organic layer was dried over sodium sulfate and evaporated to dryness in vacuo affording (+/-)-3-acetyl-2a-(2-carboxyethyl)-5-oxo-ip-cyclopentaneheptanoic acid methyl ester, 5-cyclic ethylene acetal as a mixture of the 3a and 3p isomers.

The Step 5 product (42.11 mmol) was added to 198 ml THF/r-butyl alcohol/2-methyl-2-butene, 1 1 1.3, cooled to 0°C, then treated with sodium chlorite (331.1 mmol), and sodium dihydrogen phosphate monohydrate (256.7 mmol) dissolved in 102 ml water. The biphasic solution was stirred for 10 minutes at 0°C and then 1 hour at ambient temperature and was then concentrated. The residue was diluted with 200 ml water and the pH adjusted to 3 using saturated NaHC03 solution and 1M HC1. The aqueous solution was extracted four times with THF/CH2C12, 1 2, dried with MgS04, and concentrated. The residue was purified by trituration with diethyl ether and the product isolated in 88% yield as a white solid.

Antazoline Phosphate. Aniazoline phosphate. 2- (Al-benzylanilino)methyl -2-imida/ olinc dihydrogen phosphate, occurs as a biiier, white to off-white crystalline powder that is soluble in water. It has a pK, of 10.0. and a 2Sf solution has a pH of about 4.S. Antazoline, like the etliylenediamines, contains an Al-ben/ylanilino group linked to a basic nitrogen through a two-carbon chain. 

Menadiol Sodium Diphosphate, USP. Menadiol sodium diphosphate, letrastxlium 2-methyl-1.4-nuphthalene-diol bis(dihydrogen phosphate), tetrasodium 2-mcthylnuph-thohydroquinone diphosphate, vitamin K4. is a white hygroscopic powder, very soluble in water, giving solutions with a pH of 7 to 9. It is available in ampuls for use subcutaneously, intramuscularly, or intravenously and in tablets for oral administration. Unlike the other vitamin K analogues, menadiol oral absorption does not depend on the presence of bile. Once absorbed, it is converted to inenadione.
