Baker’s yeast catalyzed Henry reaction: Biocatalytic C-C bond formation
The C-C bond formation is an important reaction in organic synthesis to obtain value-added intermediates. Therefore, in this paper an attempt has been made to accelerate the Henry reaction (C-C bond formation) between aryl aldehydes and nitromethane using less expensive whole cell biocatalyst, baker’s yeast (BY). The scope of the methodology was also tested for the heteryl aldehyde i.e. 2-chlor...

متن کاملNickel-Catalyzed Intramolecular C-O Bond Formation: Synthesis of Cyclic Enol Ethers.
An efficient and exceptionally mild intramolecular nickel-catalyzed carbon-oxygen bond-forming reaction between vinyl halides and primary, secondary, and tertiary alcohols has been achieved. Zinc powder was found to be an essential additive for obtaining high catalyst turnover and yields. This operationally simple method allows direct access to cyclic vinyl ethers in high yields in a single step.
متن کاملLigand-free nickel-catalyzed C-S bond formation: synthesis of 2-aminobenzothiazoles
A Ni-catalyzed C-S bond forming reaction has been developed for the synthesis of 2-aminobenzothiazole by the coupling of 2-haloanilines (-bromo and -iodo) with isothiocyanates. The key advantages of this procedure are ligand-free condition, inexpensive catalyst, high yields, and simple purification of the products by nonchromatographic technique.
متن کاملMetal-catalyzed carbon-sulfur bond formation.
In organic synthetic reactions, the scope and application of organosulfur chemistry have increased tremendously since sulfur-containing groups serve an important auxiliary function in synthetic sequences.1 Illustrative examples are the reversal of polarity (Umpolung), the enhancement of the acidity of C-H bonds, and the transfer of chirality from sulfur to carbon.2 On the other hand, transition...
