Catherine is from the High Peak in England. She completed her MChem with Prof. Michael Willis at the University of Oxford, and then undertook her PhD in the group of Professor Michael Greaney at the University of Manchester. She then moved to Tarragona to join the Melchiorre Group to begin research in the area of photochemical enantioselective organocatalysis. Outside of the lab, Catherine enjoys spending time with her family, walking with her dog, and reading.
From 01/03/2019 to
Food security and sustainable agriculture is a significant and current challenge to society in the face of growing global
consumption. PHOTOCHIRO seeks to provide some solutions through assisting the development of more effective crop
protection technology. Specifically, we aim at the synthesis of novel chiral amines, which are common motifs in biologically
active molecules, by using light-driven organocatalytic cascade processes. Asymmetric organocatalysis and photochemistry,
two powerful strategies of modern chemical research, have extraordinary potential for sustainably preparing the novel
organic molecules required for driving innovation in the pharmaceutical and agrichemical industries. However, the control of
enantioselectivity in photochemical processes poses a fundamental scientific challenge, and PHOTOCHIRO asks whether
asymmetric organocatalytic photochemical cascades can be used as an effective tool for the rapid synthesis of novel chiral
pyrrolidine and piperidine building blocks. The chiral molecules prepared in this project will be screened for herbicide,
insecticide, and fungicide activity in a multidisciplinary collaboration with Syngenta.
This fellowship brings a new collaboration to the host institution, transfers knowledge of advanced techniques in asymmetric
catalysis and photochemistry to the candidate, and, in addition, knowledge of these new enantioselective photocatalytic
synthetic techniques to the industrial partner. The results have the potential to increase the economic competitiveness of
Europe through Knowledge and Technology Transfer and are in line with one of H2020 Societal Challenges to secure
“viable food production in face of a growing world food demand”. The multi-cultural and intersectoral nature of this project will
broaden Dr Holden’s competencies and places her in a competitive position for her next career move.
