The Synthesis and Conformational Analyses of Some Dibenzo[3n+2]Crown-n Ethers

Abstract

The some benzo[3n+2]crowns and dibenzo[3n+2]crowns were prepared from resorsin and polyglcol dichlorides in DMSO / Water and K2CO3. The underlying non-diamond lattice of cyclic oxyethylene structures were examined with molecular mechanics, MM+ methods.
