| 4-叔丁基杯[8]芳烃 | 5,11,17,23,29,35,41,47-octakis(tert-butyl)-49,50,51,52,53,54,55,56-octakis(hydroxy)calix[8]arene | 68971-82-4 | C88H112O8 | 1297.85 |
The “paco” or “alt” isomers of acetoxylcalixarenes were selectively prepared in the presence of catalytic amount (2 mol%) of Bi(OTf)3,. Calix[4]arenes selectively gave two different isomers under specified conditions with a good selectivity, but, calix[6]arenes and calix[8]arenes only gave the “alt” isomers with a high selectivity.
