One-Pot Synthesis of Tridentate Bicyclocalixarene Cage Molecules

Organic Letters, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 18, 2025

Efficient one-pot synthesis of tridentate bicyclocalixarenes was developed by condensing phloroglucinol with dechlorinated pyrimidine or triazine a yield up to 58%. These cage-like molecules adopt symmetric three-blade propeller structure different terminal function groups and arm spans ranging from 7.5 15.8 Å. Due the 1,3-alternate configuration intermediate heterocalixarenes, cage can be prepared only benzene rings as upper lower caps. They will an ideal scaffold for preparation ultrathin two-dimensional materials.
