Reaction of pyridine derivatives with butyl glycidyl ether as a model system for glycidyl ether modified agarose : structural assignment by selective inept spectra

• The reaction of 2-thio-pyridine N-oxide, 2-amino-, 2-hydroxy, 2-thio-, and 4-thiopyridine with butyl glycidyl ether was investigated as a model system for the functionalization of 2,3-epoxypropyl activated agarose. Unambiguous structural assignment of the products was provided by selective INEPT and nuclear Overhauser difference spectra. All reactions were shown to give only one of the possible regioisomers. Further conclusions regarding the structure of the agarose derivatives were drawn from IR spectra.
