Nano CaCO3:An Unique Condensation Agent for the Preparation of Monosubstituted Calix[4]arene by Ring-opening Reaction
摘要:
Nano CaCO3 was used as a condensation agent in the ring-opening reaction of p-tert-butylcalix[4]arcnc with cpichlorohydrin to afford 5,11,17,23-tetra-tert-butyl-26,27,28-trihyd-roxy-25-(l'-chloro-2'-hydroxy-3'-propyl)calix[4]arcnc rcgiosclcctivcly in 52% yield. The yield was less lhan 2% by using normal CaCO3 instead of nano one under the same condilions.
