标 题 :Synthesis of amides and amines from aldehydes or ketones by heterogeneous metal catalysis
发明人：CÓRDOVA ARMANDO; PALO-NIETO CARLOS; AFEWERKI SAMSON
权利人:ORGANOFUEL SWEDEN AB
摘要:A mild and efficient synthesis of primary amines and amides from aldehydes or ketones using a heterogeneous metal catalyst and amine donor is disclosed. The initial heterogeneous metal-catalyzed reaction between the carbonyl and the amine donor components is followed by the addition of a suitable acylating agent component in one-pot, thus providing a catalytic one-pot three-component synthesis of amides. Integration of enzyme catalysis allows for eco-friendly one-pot co-catalytic synthesis of amides from aldehyde and ketone substrates, respectively. The process can be applied to asymmetric synthesis or to the co-catalytic one-pot three-component synthesis of capsaicin and its analogues from vanillin or vanillyl alcohol. A co-catalytic reductive amination/dynamic kinetic resolution (dkr) relay sequence for the asymmetric synthesis of optically active amides from ketones is disclosed. Implementation of a catalytic reductive amination/kinetic resolution (kr) relay sequence produces the corresponding optically active amide product and optical active primary amine product with the opposite stereochemistry from the starting ketones.

摘要:The present disclosure discloses an alcohol dehydrogenase mutant and application thereof in synthesis of diaryl chiral alcohols, and belongs to the technical field of bioengineering. The alcohol dehydrogenase mutant of the present disclosure has excellent catalytic activity and stereoselectivity, and may efficiently catalyze the preparation of a series of chiral diaryl alcohols in R- and S-configurations. By coupling alcohol dehydrogenase of the present disclosure to glucose dehydrogenase or formate dehydrogenase, the synthesis of chiral diaryl alcohol intermediates of various antihistamines may be achieved. Compared with the prior art, a method for preparing diaryl chiral alcohols through asymmetric catalytic reduction using the alcohol dehydrogenase of the present disclosure has the advantages of simple and convenient operation, high substrate concentration, complete reaction and high product purity, and has great industrial application prospects.

发明人：BROWN EDWARD G; NUSS JOHN M
权利人:CHIRON CORP
摘要:Methods for solid phase synthesis of N-alkyl amides comprise reductive amination of carbonyl compounds using a reducing agent and an amine-containing linker bound to a solid support. The methods afford high yields of linker-bound, monoalkylated amines, and subsequent coupling with acid derivatives provide derivatized N-substituted amides in excellent yields after cleavage from the solid-phase. Compositions useful in solid phase synthesis are also described.
