The invention relates to a method for producing peptoidic, peptidic and chimeric peptidic-peptoidic dendrimers by multiple iterative multi-component reactions (MCR), in particular Ugi or Passerini multi-component reactions, to compounds produced in this way and to the use thereof.
known, the heterocyclic imines 2,5-dihydro-1,3-thiazoles are convertible to bisamides with the aid of a carboxylic acid and an isocyanide (Ugi reaction). Herein, it is shown that 2,5-dihydro-1,3-thiazole S-monoxides-the respective alpha-sulfinyl imines-are characterized by an altered reaction behavior. In a hitherto unknown multicomponent reaction the alpha-sulfinyl imines react with an isocyanide
advantages of our methodology include an increased synthesis speed, very mild conditions giving access to hitherto unknown or highly reactive classes of isocyanides, rapid access to large numbers of functionalized isocyanides, increased yields, high purity, proven scalability over 5 orders of magnitude, increased safety and less reaction waste resulting in a highly reduced environmental footprint. For example

the Ugi‐reaction has been developed. This syntheticapproach of just two steps is unprecedented, short, efficient and works over a wide range of medium (8–11) and macrocyclic (≥12) loop sizes. The substrate scope and functional group tolerance is exceptional. Using this approach, we have synthesized 39 novel macrocycles by two or even one single synthetic operation. The properties of our macrocycles

mmol scale synthesis on 96-well format and on a high-throughput nanoscale format in a highly automated fashion. High-throughput PX of our libraries efficiently yielded potent covalent inhibitors of the main protease of the COVID-19 causing agent, SARS-CoV-2. Our results demonstrate, that the marriage of in situ HT synthesis of (covalent) libraires and HT PX has the potential to accelerate hit finding
