Conversion of pyridinoline to deoxypyridinoline

摘要

The present invention involves the synthetic conversion of pyridinoline (PYD) to deoxypyridinoline (DPD) via an intermediate ester which is subsequently cleaved. The transformation of PYD into a xanthate-type ester intermediate facilitates the subsequent removal of the substituted hydroxyl functionality thus providing the desired DPD. The method provides a new chemical pathway for the preparation of DPD, resulting in significantly increased yields as compared to traditional methods of product isolation.
