A Tandem [3+2] Cycloaddition-Elimination Cascade Reaction to Generate Pyrrolo-[3,4-c]pyrrole-1,3-diones
摘要:
An efficient tandem [3+2] cycloaddition-elimination cascade sequence has been developed enabling assembly of the pharmacologically relevant pyrrolo-[3,4-c]pyrrole-1,3-dione chemotype. The strategy involves simple mixing of readily accessible oxazolin-2-ones and pyrrole-2,5-diones in the presence of base under mild conditions, rendering the title compounds in typically excellent yields. Of note, this route allows for installation of three points of diversity and is ideal for combinatorial applications and parallel synthesis production campaigns.

design, we have developed novel, potent, and specific DFG-out allosteric inhibitors of B-Raf kinase. Here, we present efficient and versatile chemistry that utilizes a key one pot, [3+2] cycloaddition reaction to obtain highly substitutedimidazoles and their application in the design of allosteric B-Raf inhibitors. Inhibitors based on this scaffold display subnanomolar potency and a favorable kinase
