Journal Article
Martínez, J. I., Groves, A., Martinez, J. I., Smith, J. J., & Lam, H. W. (2018). Remote Nucleophilic Allylation by Allylrhodium Chain Walking. Chemistry - A European Journal, 24(51), 13432-13436. https://doi.org/10.1002/chem.201803574

Metal migration through a carbon chain is a versatile method for achieving remote functionalization. However, almost all known examples involve the overall net migration of alkylmetal species. Here, we report that allylrhodium species obtained from h... Read More about Remote Nucleophilic Allylation by Allylrhodium Chain Walking.

Enantioselective synthesis of chiral cyclopent-2-enones by nickel-catalyzed desymmetrization of malonate esters (2018)

The enantioselective synthesis of highly functionalized chiral cyclopent‐2‐enones by the reaction of alkynyl malonate esters with arylboronic acids is described. These desymmetrizing arylative cyclizations are catalyzed by a chiral phosphinooxazoline...
