A New Strategy for the High-Pressure Synthesis of Chiral Cryptands

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.

SYNTHESIS OF NOVEL CHIRALCRYPTANDS INCORPORATING SUGARS

Chiral N,N'-dimethyl diaza-crown ethers bearing functionalized α-D-gluco-, α-D-galacto-, and α-D-mannopyranoside residues are transformed into the corresponding cryptands with bis(2-iodoethyl) ether under high-pressure conditions and subsequent de

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.
