A Novel Calix [4] arene Having Long-Chain Monoalkenyl at The Upper Rim
摘要:
5-1',1'-dimethylundecenyloxyphenylmethyl-11,17,23-tris-1",1"-dimethylethyl-25,26,27,28-tetrahydroxycalix [4] arene was synthesized from 1,1-dimethylundecenyoxylphenyl-methylphenol (3) and bishydroxymethylated p-tert-butylphenol-formaldehyde trimer (7) (3-[3-[3-(Hydroxymethyl)-5-tert-butylsalicyl-5]-tert-butylsalicy]-5-tert-butyl-2-hydroxybenzyl Alcohol) by ‘1+3’ fragment condensation in dioxane with TiCl4 as condensation agent in 28% yield.It is the first long-chain monoalkenyl substituted calix [4] arene in which the alkenyl was attached to the upper rim of calix [4] arene.
