| —— | 5,11,17,23-tetra-t-butyl-25,26,27,28-tetrahydroxycalix-4-arene | 288302-12-5 | C44H56O4 | 648.926 |
Mono-, di-, tri- and tetra-O-arylmethyl-p-t-butylcalix[4]arenes were synthesised respectively from p-t-butylcalix[4]arene and arylmethyl bromide through an easy and selective one-step reaction. Mono- and di-arylmethyl ethers of p-t-butylcalix[4]arenes were prepared using LiH as a base, while tri- and tetra-arylmethyl derivatives were afforded in the presence of Ba(OH)2 and BaO. These methods are remarkable for excellent selectivity, mild reaction conditions, moderate to good yields and easy purification.
