Abstract

Reactions between tripodal CH3C(CH2NH2)3 = 'tame' and CH3C(CH2NHCH2CH2NH2)3 = 'sen' with the monomethoxycarbonylmethyl ether 1 lead to the ready isolation of tame-dicalix 2, tame-tricalix 3 and sentricalix 4. Studies of complex formation of 3 and 4 with Zn(II) showed that 'tame' residue is incapable of coordinating the metal in its N3 donor site, while Zn(II) is preferentially coordinated in the carbomethoxyamido functions and two hydroxyl groups of the calix[4]units of 4.
