The chemistry in this proposal involves the development of a series of cascade processes based on combinations of C-N, C-O, C-S and C-C coupling reactions, mediated by copper and palladium based catalysts, to deliver a variety of functionalised heterocyclic products. Significant variation of the heterocyclic core and the nature and position of the substituents will be possible employing what is essentially a single strategy. Although the individual reactions used to construct these cascades are well established, it is the ability to combine them in productive processes that will allow valuable drug-like molecules to be produced. Cascades of C-X bond forming reactions offer great potential for heterocycle synthesis as they the introduction of the functional groups and heteroatom combinations frequently encountered in drug-like molecules. Cascade sequences involving up to four bond forming processes will be used to prepare complex, drug-like molecules in a single step. A significant aspect of the chemistry involves demonstrating that it can be applied to array synthesis.

该提案中的化学涉及开发一系列基于C-N、C-O、C-S和C-C偶联反应组合的级联工艺，由铜和钯基催化剂介导，以提供各种官能化的杂环产物。杂环核心以及取代基的性质和位置的显著变化将可能采用基本上单一的策略。虽然用于构建这些级联的各个反应已经很好地建立，但是在生产过程中将它们联合收割机结合的能力将允许产生有价值的药物样分子。C-X键形成反应的级联为杂环合成提供了巨大的潜力，因为它们引入了在药物样分子中经常遇到的官能团和杂原子组合。涉及多达四个键形成过程的级联序列将用于在一个步骤中制备复杂的药物样分子。化学的一个重要方面涉及证明它可以应用于阵列合成。
