  Inherently chiral calix[4]arenes with asymmetrical superposition of substituents at the lower and the upper rims of macrocycle

  摘要：

  Three types of inherently chiral calix[4]arenes (AAHH(BHBH), AHHH(HBBH) , AAHH(HHBH)) with asymmetrical superposition of ethyl, diethoxyphosphoryl groups at the lower rim of the macrocycle and bromine atoms at the upper rim, have been synthesized. The key steps of the synthesis are O,O'-phosphorotropic rearrangements of 1,3-distally disubstituted calix[4]arenes into 1,2-proximal isomers, regioselective bromination of the upper rim and hydrolytic removing of phosphoryl or benzoyl group from the lower rim.

  Inherently chiral phosphoruscontaining calix[4]arenes with asymmetrical placement of substituents at the macrocyclic lower rim (phenolic oxygen atoms) as well as with asymmetrical superposition of substituents at the upper rim (para-positions of benzene rings) and at the lower rim have been synthesized. The key steps of the synthesis are O,O-phosphorotropic rearrangements of 1,3-distally disubstituted

• Symmetrical and inherently chiral water-soluble calix[4]arenes bearing dihydroxyphosphoryl groups

  A series of symmetrical and inherently chiral water-soluble calix[4]arenes bearing one, two or four proton-ionisable dihydroxyphosphoryl groups at the narrow rim of the macrocycle has been synthesised by consecutive treatment of appropriate diethoxyphosphoryl derivatives with bromotrimethylsilane and methanol. The calix[4]arene phosphoric acids synthesised possess pKa-values 2.85–3.10 (CH3OH–H2O 70 : 30) and form salts with L-(−)-α-phenylethylamine or (1S,2R)-(+)-ephedrine in methanol solution. The salts of the inherently chiral calixarene phosphoric acids with chiral amines are easily separated into diastereomeric forms by the RP HPLC method on Separon SGX C18 or Partisil 5 ODS 3 achiral columns.
