enantioselectivity and activity. The effect of the addition of organic solvents to the biotransformation mixture was also determined. The results of the study suggested that SET1 is suitable for use in selected organo‐aqueous media at specific ratios only. The functional group tolerance of the isolate with unprotected and protected β‐aminonitriles, structural analogues of β‐hydroxynitriles was also investigated
Catalytic Enantioselective Decarboxylative Cyanoalkylation of Imines by Using Palladium Pincer Complexes with<i>C</i><sub>2</sub>-Symmetric Chiral Bis(imidazoline)s
Manifold products: The enantioselective decarboxylative Mannich‐type reaction of cyanoacetic acid with N‐ (2‐pyridinesulfonyl)imines catalyzed by chiral 1,3‐bis(imidazolin‐2‐yl)benzene (Phebim)–PdII complexes afforded products with good enantioselectivity (see scheme). The reaction was applied to a wide range of imines with good yield and enantioselectivity. The obtained products can be converted into

The Ugi reaction is applied for the preparation of (R)-lacosamide, an important drug for the treatment of epilepsy. To this end, key issues associated with the Ugi reaction, such as a practical preparation of the foul-smelling isocyanide as well as the efficient introduction of chirality via a cheap and easily removable chiral directing:group, were solved. Enantiomerically pure (>99.9% ee) drug substance meeting all required purity specifications is prepared in operationally simple four steps, in 40% overall yield from the commodity chemical benzylamine.
