Hydroxynitrile Lyases, Interesting Biocatalysts in Stereoselective Organic Syntheses
Hydroxynitrile lyases (HNLs) from Prunus amygdalus (PaHNL), Sorghum bicolor (SbHNL), Manihot esculenta (MeHNL) and Hevea brasiliensis (HbHNL) are excellent biocatalysts for the preparation of optically active cyanohydrins. (R)as well as (S)-cyanohydrins are obtained in high optical and chemical yields. The synthetic potential of the now easily available optically pure cyanohydrins is demonstrat...
متن کاملEfficient Synthesis and Analysis of Chiral Cyanohydrins
This thesis deals with the development of new methods for efficient synthesis and analysis in asymmetric catalysis. It focuses on the preparation of chiral cyanohydrins by enantioselective addition of cyanide to prochiral aldehydes. The initial part of the thesis describes the development of a dual Lewis acid– Lewis base activation system for efficient synthesis of chiral O-acylated and Ocarbon...
متن کاملSynthesis and Reactions of Optically Active Cyanohydrins
Franz Effenberger * . Cyanohydrins have always held a place of importance both as technical products and as reagents in organic chemistry. It is surprising. therefore. that optically active cyanohydrins have been extensively investigated and employed for syntheses relatively recently. This can be explained by the fact that only in the past few years have enzymatic methods made chiral cyanohydri...
متن کاملConvergent, stereoselective syntheses of the glycosidase inhibitors broussonetines D and M.
The first syntheses of the polyhydroxylated alkaloids (iminosugars) broussonetines D and M, glycosidase inhibitors of the pyrrolidine class, have been performed in a convergent, stereocontrolled way from D-serine as the chiral starting material. A cross metathesis step was one key feature of the synthesis. The versatility of the synthetic concept chosen permits the access to many members of thi...
متن کاملStereoselective syntheses of fluorescent non-natural aromatic amino acids based on asymmetric Michael additions.
Four fluorescent non-natural aromatic amino acids have been synthesized based on a key stereoselective Michael addition reaction. S-1-phenylethylamine was employed as both the source of amine and the stereoselectivity controller. The overall yields were moderate (30-50%). Fluorescent properties of some of the fluorophores were also investigated. It was found that compounds with a dimethylamino ...
