Abstract

Reactions between tripodal CH3C(CH2 NH2)3 = 'tame' and CH3C (CH2 NHCH2 CH2 NH2)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 carbomethoxy-amido functions and two hydroxyl groups of the calix[4]units of 4.
