Recent developments in automated structure elucidation of natural products

Advancements in the field of Computer-Assisted Structure Elucidation ( CASE) of Natural Products achieved in the past five years are discussed. This process starts with a dereplication procedure, supported by structure-spectrum databases. Both commercial and free products are available to support the procedure. A number of new programs, as well as advancements in existing ones, are presented. Finally, the option to validate the result by an independent procedure, a high quality ab initio quantum mechanical calculation, is discussed.
