The ability of chemists to invent new transformations is at heart of our modern society, as novel chemical methods to forge bonds with increased precision and selectivity enable more efficient preparation of materials, medicines, agrochemicals and fine chemicals. Catalysis is a powerful tool to devise new reactions and render the existing ones more selective, thus contributing to a more sustainable use of natural resources. In this context, the present PhD project merges in original ways elements taken from both organo- and transition-metal catalysis, to open new paths for stereoselective reactions of unsaturated feedstock substrates and for sustainable synthesis oriented to medicinally relevant scaffolds.The PhD student will design and prepare novel organocatalysts capable of engaging with common metal halide (pre)catalysts via non-covalent interactions. These binary catalytic systems will then be employed in a large variety of reactions to achieve increased rate, unusual regio- and stereoselectivity and/or unprecedented levels of enantiocontrol starting from minimally functionalised, electronically unbiased substrates.

化学家发明新转化的能力是我们现代社会的核心，因为以更高的精度和选择性形成化学键的新化学方法能够更有效地制备材料、药物、农用化学品和精细化学品。催化是设计新反应并使现有反应更具选择性的强大工具，从而有助于更可持续地利用自然资源。在此背景下，本博士项目以原创方式融合了有机催化和过渡金属催化的元素，为不饱和原料底物的立体选择性反应和面向医学相关支架的可持续合成开辟了新的途径。博士生将设计并制备能够通过非共价相互作用与常见金属卤化物（预）催化剂结合的新型有机催化剂。然后，这些二元催化系统将被用于各种各样的反应中，以从最低限度功能化的、电子无偏的底物开始，实现更高的速率、不寻常的区域选择性和立体选择性和/或前所未有的对映体控制水平。
