Synthesis of chiral pyrrolidine and pyrrole derivatives through the chemoselective Dieckmann reaction of α,β-aminodiesters
摘要:
alpha,beta -Aminodiesters were allowed to react with t-BuOK in THF at -78 degreesC. The chemoselectivity of the Dieckmann cyclization was controlled by the nature of the substituents R-3 and R-4, allowing the preparation of pyrrolidine or pyrrole derivatives.

Compounds of formula (I), imidazopyrimidine ketones, as well as preparations and applications thereof. Compounds and pharmaceutically acceptable salts thereof which stimulate the body to produce tumor necrosis factor-related apoptosis-inducing ligands, while avoiding the drawbacks of existing cancer treatments based on recombinant proteins and antibodies. Thus, they can provide novel options for the treatment of related tumors.
