Bio-Based Amides from Renewable Isosorbide by a Direct and Atom-Economic Boric Acid Amidation Methodology

The functionalization of bio-sourced isohexides has proved challenging over the last number of years, especially in polymer and medicinal chemistry. We report herein the synthesis of bio-based amido-isohexides by the known boric acid catalysed amidation reaction. The coupling reaction was successfully performed with aliphatic and aromatic carboxylic acids. The extension of the scope of the reaction to eight Boc-protected amino acids is also described, the products being obtained in moderate to good yields. A preliminary screening of these new potential organocatalysts was carried out for the aldolization of isatin. We describe herein the formation of the amide bond between amines derived from dianhydrohexitols and carboxylic or amino acids mediated by a catalytic quantity of boric acid.

Dianhydrohexitols: New tools for organocatalysis. Application in enantioselective Friedel-Crafts alkylation of indoles with nitroalkenes

A series of hydrogen bonding organocatalysts was synthesized from dianhydrohexitol and was used for the first time in organocatalysis for Friedel-Crafts alkylation of indoles with nitroalkenes. Moderate yields and enantioselectivities were achieved. ARKAT

Direct amination of bio-alcohols using ammonia

A slightly adapted catalyst system has been successfully applied in the direct amination of primary and secondary alcohols. Moreover, the applicability to diols has been shown, giving high selectivity towards the primary diamines. It was found that the Ru/P ratio as well as the amount of ammonia used are highly important in this system, especially for higher substrate loadings. The catalyst was employed on a larger batch scale for the conversion of isomannide to the corresponding diamine. Additionally, it was shown that the catalyst is stable for at least six consecutive runs. No significant loss of activity and selectivity was observed.

Improved ruthenium-catalyzed amination of alcohols with ammonia: Synthesis of diamines and amino esters

Diamination of diols: The first homogeneously catalyzed diaminations of primary and secondary diols with ammonia give the corresponding diamines. Other primary as well as secondary alcohols including hydroxy-substituted esters can also be efficiently converted to primary amines. This atom-efficient and selective amination method proceeds in an ammonia atmosphere without additional hydrogen sources. Copyright
