  Unusual Regioselectivity of the Dipolar Cycloaddition Reactions of Nitrile Oxides and Tertiary Cinnamides and Crotonamides¹

  摘要：

  Benzonitrile oxides undergo 1,3-dipolar cycloaddition reactions with methyl cinnamate to produce the 5-phenyl and 4-phenyl regioisomers in approximately an 80:20 ratio. However, use of N,N-diethylcinnamide as the dipolarophile unexpectedly resulted in the formation of the 5-phenyl and 4-phenyl regioisomers in a 23:77 ratio. Studies have shown that this phenomena occurs only for tertiary cinnamides, In addition, it has been demonstrated that the phenyl group of tertiary cinnamides is not essential for the reversal of regioselectivity since crotonamides produce the same results and trends as the cinnamides. However, since acrylates and acrylamides both produce the 5-carbonyl regioisomers, it can be concluded that the beta-substituent is playing a key role for the unexpected results by possibly increasing steric interactions between the dipole and dipolarophile in the transition state. Transition state energies were calculated for the regioisomeric cycloadduct pairs derived from several crotonamides as well as methyl crotonate. These calculations indicate that steric factors are indeed responsible for the reversal of regioselectivity.

  通用的生物合成方法来形成酰胺键

  摘要：

  通用和可持续的酰胺键形成催化策略的开发是制药行业和更广泛的化学工业的主要目标。在这里，我们报告了一种酰胺合成的生物催化方法，该方法利用了自然界中形成酰胺键的酶，N-酰基转移酶（NAT）和CoA连接酶（CL）的多样性。通过选择具有所需底物特征的NAT和CL的组合，可以以可预测的方式构建非天然的生物催化途径，以允许使用化学计量比的羧酸和胺偶联伙伴以高收率获得结构多样的仲和叔酰胺。可以使用分离的酶在体外或体内进行转化反应仅依赖于细胞产生的辅因子。这些全细胞系统的实用性通过Losmapimod的关键中间体（GW856553X）的制备规模合成得到展示，Losmapimod是一种选择性的p38促分裂原活化蛋白激酶抑制剂。

  synthesis of amides has been explored by using secondary alcohols, Cu(ClO4)2·6H2O as a catalyst, and trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) at ambient temperature. This method has been successfully adapted to the preparation of azides directly from their corresponding alcohols and offers excellent chemoselectivity in the formation

  The present invention relates to a method for synthesising amides that is of general applicability. The method may be performed in vitro or in vivo. Cell lines for use in the in vivo methods also form aspects of the invention. The method for synthesising a non-natural amide comprises: a. reaction of a carboxylic acid with a naturally occurring CoA ligase or a variant thereof; and b. reaction of the product of step a with an amine in the presence of a naturally occurring acyltransferase or a variant thereof; with the proviso that where the CoA ligase and acyltransferase are both naturally occurring, they are not derived from the same source species and do not act sequentially in a metabolic pathway; and with the proviso that the non-natural product is not N-(E)-p-coumaroyl-3-hydroxyanthranilic acid or N-(E)-p-caffeoyl-3-hydroxyanthranilic acid. Further, a method for producing an active pharmaceutical ingredient by the aforementioned method and host cells for carrying out said methods are envisaged.
