Description	New types of lower rim proximally bridged thiacalix[4]arenes have been prepared by direct aminolysis of starting tetraacetate derivative in the cone conformation using aliphatic ?,?-diamines. X-ray crystallography revealed the highly preorganized array of -C(O)NH- bonds resulting in strong intramolecular hydrogen bonding between amide groups of both bridges. The length of the corresponding diamine was found to have an essential influence on the yield of these bridged molecules.

Strukturní analýza ukázala síť intramolekulárních vodíkových vazeb mezi amidickými skupinami obou spojek. Délka odpovídající diaminu má značný vliv na výtěžek reakce. (cs)
