Synthesis, structure and spectroscopic properties of calix[4]phloroglucinarene dodecamethyl ether and its trifluoroacetic acid complex

The action of trifluoroacetic acid (TFA) on 2,4,6-trimethoxybenzyl alcohol 3 affords the title tetrameric compound in high yield as a maroon TFA complex, 4 ; trituration of which with acetone gives the free, colorless, calix[4]phloroglucinarene ( 5 ) that can also be directly isolated by treating th...
