Calix[4]bis(spirodienone) as a versatile synthon for upper rim alkoxylation of calixarenes and synthesis of novel triazole-based biscalixarene by 'CuAAC' chemistry

The spiro rings of calix[4]bis(spirodienone) have been opened up using various bromofunctionalised alcohols employing a novel ipso nucleophilic substitution of tert-butyl groups by alkoxy groups. Additionally, a route has been paved towards the preparation of triazole-linked biscalixarene via the copper(I)-catalysed modern version of classical Huisgen 1,3-dipolar cycloaddition of alkynyl calixarene and azidocalixarene, derived from the above-mentioned bromo-substituted calixarene.

A novel method for the upper rim alkoxy-substitution of calix[4]arene via a bis(spirodienone) route

A mild and efficient one-step procedure for the upper rim modification of calix[4]arene via a bis(spirodienone) is described. The bis(spirodienone) on reaction with alcohols in the presence of p-TSA affords mono- and 1,3-disubstituted alkoxy derivatives i
