11. Laboratory synthesis of febrifugine determined that the originally reported stereochemistry was incorrect. 12. The stereochemistry in Scheme 1 is shown three-dimensionally. 13. One limitation relates to the stereochemistry of the product. 14. In early work with Dwyer and throughout his career, he studied stereochemistry . 15. The result from intramolecular proton delivery is the reverse of the common stereochemistry . 16. Enantiopure oxaziridines where stereochemistry is entirely due to configurationally stable nitrogen are reported. 17. Its stereochemistry is identical to the stereochemistry of elisabethatrienol. 18. Its stereochemistry is identical to the stereochemistry of elisabethatrienol. 19. Laevarotatory describes the stereochemistry of the molecule, while mandelonitrile refers to its chemical identity 20. The quality of stereoselectivity is concerned solely with the products, and their stereochemistry .
