A Contribution to the Structural Assignment of Positional Isomers of Bis-galacto and Bis-manno Crown Ethers

A structural assignment to the positional isomers of bis-galacto 3/4 and bis-manno crown ethers 6/7 is not possible using spectroscopic data only.Crown ethers 3 and 6 with a 3/3' and 2/2'conjunction of the two sugar moieties are available rationally via the "half crowns" 11 and 13 and are thus identifiable.

Synthesis and Formation of Complexes of Crown Ethers from Methyl 4,6-O-Benzylidene-α-D-glucopyranoside

A new method for the synthesis of the isomers A and B of the crown ether 3 in a two phase system is described, Starting from 3B the derivatives 5 with different solubility and complex forming characteristics have been prepared.
