New synthetic strategies leading to highly functional erythrina, oxindole and pyrrolidinoindoline skeletons have been developed and an efficient formal syntheses of (+/-)-demethoxyerythratidinone reported.
In the presence of catalytic amount of copper salt, an efficient and flexible synthetic method towards the synthesis of a structurally new type of spirocyclic lactams was developed.
New oxidative dearomatization procedures leading to Spiro beta-lactams and oxindoles were developed. By a variation of the oxidative reaction conditions, the usefulness of phenolic amides, derived from 4-aminophenol, in the synthesis of structurally different types of molecules was demonstrated.
Homochiral Metal–Organic Frameworks with Enantiopure Proline Units for the Catalytic Synthesis of β-Lactams
Two enantiopure organic ligands integrating flexible proline units and rigid isophthalate units have been rationally designed and employed for the construction of four homochiral porous metal-organic frameworks (MOFs), respectively. One pair of these MOFs is used as heterogeneous catalysts to construct beta-lactam derivatives by oxidative coupling reactions.
