The present invention is broadly directed to novel compounds useful for the synthesis of biologically active compounds. More particularly, the present embodiments disclosed herein relate to novel side chains, that when coupled to a taxane, are useful for the synthesis of pharmaceutically useful taxanes. Methods of forming the novel side chains and coupling them to hindered alcohols, namely taxanes resulting in useful esters are also disclosed. Various taxanes compounds are known to exhibit anti-tumor activity.
