Schiff base calixarenes
Four different synthetic routes to the sub-target, the p-tert-butylcalix[4lethylamine (6a) from thep-tert-butylcalix[4]arene (1a) have been examined. The best one was a 5-step synthesis, which gave an overall yield of65%. p-tert-Butylcalix[6]ethylamine (6b) and p-tert-butylcalix[8]ethylamine (6c) we...
