A new efficient method for the preparation of 2,6-pyridinedimethyl ditosylates from dimethyl 2,6-pyridinedicarboxylates

Article abstract of DOI:10.1080/00397919908086011

We report here an efficient method for the preparation of 2,6- pyridinedimethyl ditosylate and four of its 4-substituted derivatives, two of them have not been reported in the literature. We also describe here a modification of the reported synthesis for chelidonic and chelidamic acids with improved yields and higher purity.
