Silver Nitrate-Catalyzed Isocyanide Insertion/Lactamization Sequence to Imidazolones and Quinazolin-4-ones: Development and Application in Natural Product Synthesis

Qian Wang, Jieping Zhu, Antonin François Roland Clemenceau

Silver nitrate-catalyzed reaction of methyl α,α-disubstituted α-isocyanoacetates with primary amines afforded 3,5,5-trisubstituted imidazolones in good to excellent yields. A silver salt-catalyzed insertion of the isocyano group into the N−H bond of the am ...

Around isocyanide reactivity : development of enantioselective transformations and syntheses of heterocycles and natural products

Antonin François Roland Clemenceau

This manuscript covers two main topics. The first part dealt with the organocatalytic conjugate addition of Michael donors to phenyl vinyl selenone. The enantioselective Cinchona alkaloid-catalyzed Michael addition using a-substituted a-nitroacetates has b ...

Enantioselective Synthesis of Quaternary α-Amino Acids Enabled by the Versatility of the Phenylselenonyl Group

Qian Wang, Jieping Zhu, Antonin François Roland Clemenceau

A novel Cinchona alkaloid-catalyzed enantioselective conjugate addition of alpha-alkyl substituted alpha-nitroacetates to phenyl vinyl selenone was developed. The resulting enantio-enriched alpha,alpha-dialkyl substituted alpha-nitroacetates were subsequen ...
