1,3-Dialkoxycalix[4]arenes 1-3 in Et2O give diacetylated derivatives in the fixed cone conformation with AcCl/NaH, whereas the stereoisomeric compounds in the partial cone structure are produced in high yield using AcCl/EtOTl.

Abstract
1,3-Dialkoxycalix[4]arenes 1-3 in Et2O give diacetylated derivatives in the fixed cone conformation with AcCl/NaH, whereas the stereoisomeric compounds in the partial cone structure are produced in high yield using AcCl/EtOTl.File in questo prodotto:
