Abstract
Official abstract text for this publication.
The invention relates to (among other things) non-ring hydroxy substituted taxanes and methods for synthesizing the same. The invention further relates to conjugating the non-ring hydroxyl substituted taxanes to a water-soluble, non-peptidic polymer.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising esterifying a baccatin III compound of Formula III, which compound is encompassed by the formula: wherein: R 1 is selected from the group consisting of H, a hydroxy protecting group, a C 1-6 organic radical; R 2 is selected from the group consisting of H, a hydroxy protecting group, a C 1-6 organic radical; and R 3 is…
