A series of large-ringed calix[6,7,8]arene analogues have been synthesised and their affect against Mycobacterium tuberculosis in vivo established. In general, when p-phenylcalixarenes and tert-butylcalixarenes were not functionalised at the lower rim, low biological activities were observed. However on going from partially to fully lower rim pegylated calixarenes the anti-mycobacterial properties improved. The addition of cyanopropoxy groups at the lower rim gave rise to low activities, whereas the addition of acetate moieties interestingly had pro-TB effects. Two upper rim sulfonated calixarenes showed promising properties. In the course of this work, a high yielding procedure to synthesise p-phenylcalix[7]arene was also established. Copyright

p-Phenylcalix[4]arene is formed directly fromp-phenylphenol in 66% yield (50% isolated yield) using poly(ethylene glycol) as the reaction medium, with crystallization of the pure cavitand from toluene mediated by p-earborane. The solid-state structure comprises interlocking columnar arrays. CSIRO 2006.
Direct synthesis of calixarenes with extended arms: p-phenylcalix[4,5,6,8]arenes and their water-soluble sulfonated derivatives

p-Phenylcalix[4,5,6,8]arenes have been isolated from the base catalysed condensation of p-phenylphenol with formaldehyde in tetralin, and selectively converted to the corresponding sulfonated derivatives using sulfuric or chlorosulfonic acids.

The base-induced condensation of p-phenylphenol and formaldehyde is shown to yield p-phenylcalixarene 3 and p-phenylcalixarene 5 as isolable products but no detectable amount of p-phenylcalixarene 1, contrary to earlier reports.As an alternative
