A new strategy for the high-pressure synthesis of chiral cryptands is reported.Four chiral cryptands derived fro D-glucose, D-galactose, D-mannose and L-tartaric acid are prepared in a short reaction sequence.
High-pressure Approach to the Synthesis of Novel Chiral Cryptands Derived from Methyl 4,6-O-Benzylidene-α-D-manno-, -α-D-galacto-, and -α-D-gluco-pyranoside

Diaza crown ethers derived from sugars react under high pressure with bis-(2-iodoethyl) ether to give the quaternary salts in quantitative yield and their subsequent demethylation with triphenylphosphine affords chiral cryptands in high yield.
