  • Phase-Transfer-Catalyzed Asymmetric Conjugate Cyanation of Alkylidenemalonates with KCN in the Presence of a Brønsted Acid Additive
    作者:Yan Liu、Seiji Shirakawa、Keiji Maruoka
    DOI:10.1021/ol400143m
    日期:2013.3.15
    Highly enantioselective conjugate cyanation of alkylidenemalonates with KCN was achieved under mild phase-transfer conditions with a bifunctional phase-transfer catalyst. The effect of Brønsted acid additives was examined based on the hypothetical catalytic cycle, and the Brønsted acid additive was found to be essential to promote the conjugate cyanation efficiently.
    在温和的相转移条件下,使用双功能相转移催化剂可实现亚烷基丙二酸酯与KCN的高度对映选择性共轭化。基于假设的催化循环检查了布朗斯台德酸添加剂的效果,发现布朗斯台德酸添加剂对于有效地促进共轭化是必不可少的。

  • Development of a Chemoenzymatic Manufacturing Process for Pregabalin
    作者:Carlos A. Martinez、Shanghui Hu、Yves Dumond、Junhua Tao、Patrick Kelleher、Liam Tully
    DOI:10.1021/op7002248
    日期:2008.5.1
    A new manufacturing process for (S)-3-(aminomethyl)-5-methylhexanoic acid (Pregabalin), the active ingredient in Lyrica, has been developed. Using Lipolase, a commercially available lipase, rac-2-carboxyethyl-3-eyano-5-methylhexanoic acid ethyl ester (1) can be resolved to form 2-carboxyethyl-3-cyano-5-methylhexanoic acid (2). A heat-promoted decarboxylation of 2 efficiently generates (S)-3-cyano-5-methylhexanoic acid ethyl ester (3), a known precursor of Pregabalin. This new route dramatically improved process efficiency compared to the first-generation process by setting the stereocenter early in the synthesis and enabling the facile racemization and reuse of (R)-1. The chemoenzymatic process also reduced organic solvent usage resulting in a mostly aqueous process. Compared to the first-generation manufacturing process, the new process resulted in higher yields of pregabalin (40-45% after one recycle of (R)4), and substantial reductions of waste streams corresponding to a 5-fold decrease in the E factor from 86 to 17.
