Abstract

Abstract Highly specific biocatalytic reactions have been used to create a population of derivatives from a single starting compound. Examples demonstrate synthesis of derivatives of taxol, taxol-2'-adipate, taxol-2'-vinyl adipate, 2,3-(methylenedioxy) benzaldehyde, (±)-(2-endo, 3-exo)-bicyclo (2.2.2)octo-5-ene-2,3-dimethanol, adenosine and erythromycin.
