well known biocatalysts for the asymmetric synthesis of α‐hydroxy ketones with preferential (R)‐selectivity. Pharmaceutically relevant phenylacetyl carbinol (PAC) has been prepared with absolute (S)‐configuration only on a few occasions using enzyme variants suitably designed through rational site‐directed mutagenesis approaches. Herein, we describe the synthesis of (S)‐phenylacetyl carbinol products with
(S)-Phenylacetylcarbinol [(S)-PAC] and its derivatives are valuable intermediates for the synthesis of various APIs (active pharmaceutical ingredients), however their selective synthesis is challenging. As no highly selective enzymes or chemical...

Insight into the Stereoselective Synthesis of (1<i>S</i>)‐Nor(pseudo)ephedrine Analogues by a Two‐Steps Biocatalytic Process
The stereodivergent synthesis of variously substituted norephedrines has been attained starting from the cheap and commercially available corresponding aromatic aldehydes through a bi-enzymatic synthetic sequence. In the first step, a benzoin-type condensation is mediated by the (S)-selective acetoin:dichlorophenolindophenol oxidoreductase (Ao:DCPIP OR), while in the second step either a (R)- or a
各种取代的去甲麻黄碱的立体发散合成已经通过双酶合成序列从廉价且市售的相应芳香醛开始实现。在第一步中,安息香型缩合由 ( S )-选择性乙偶姻:二氯苯酚靛酚氧化还原酶 (Ao:DCPIP OR) 介导,而在第二步中,则由 ( R )- 或 ( S )-氨基转氨酶 ( ATA)用于进行氨基转移并获得最终产品。 14 种底物阵列与 6 种不同的 ATA 相结合,并根据转化率和对映体过量对产品进行了表征。
A ChemoEnzymatic Approach for the Preparation of “Linear‐Shaped” Diaryl Pyrazines as Potential Antiprotozoal Agents
chemoenzymatic route comprising a biocatalyzed benzoin condensation reaction and a transaminase-mediated tandem process of transamination and cyclization. The obtained pyrazines were tested for their potential leishmanicidal and antiplasmodial activity in vitro.
