Syntheses and Binding Properties of Calix[4]arene Derivatives with Semicarbazone and Benzalazine Groups;

The mono or disemicarbazone can be obtained by the control of the ratio of α ketohemithioacetal and semicarbazide.

Propionyl ferrocene reacted with 4-substituted semicarbazides converted into corresponding semicarbazones 1-8, which are not prepared previously.

(Thia)calix[4]arene thiosemicarbazone derivatives 5a and 5b were synthesized by "1+2" con-densation of 1,3-bis[2-(p-formylphenyloxy)ethyloxy]-p-tert-butylcalix[4]arene 4a and 4b with 1-phenyl-thiosemicarbazide in yields of 84% and 85%,respectively.
