  通过平行动力学不对称转化外消旋环己二酮的对映发散环化

  摘要：

  有机合成中迫切需要将可用的外消旋底物完全转化为有价值的对映体富集产物的策略。本文报道了外消旋环己二酮的第一个平行动力学不对称转化。外消旋环己二酮首先非对映选择性地转化为一对新的外消旋瞬态二烯醇中间体，然后通过手性磷酸平行质子化，得到两组带有四元立构中心的氢吲哚产物，通常具有优异的对映选择性。

  An object of the present invention is to provide a process that enables isocyanates to be stably produced over a long period of time at high yield without encountering various problems as found in the prior art when producing isocyanates without using phosgene. The present invention discloses a process for producing an isocyanate, comprising the steps of: reacting a carbamic acid ester and an aromatic hydroxy compound to obtain an aryl carbamate having a group derived from the aromatic hydroxy compound; and subjecting the aryl carbamate to a decomposition reaction, wherein the aromatic hydroxy compound is an aromatic hydroxy compound which is represented by the following formula (1) and which has a substituent R 1 at least one ortho position of a hydroxyl group: (wherein ring A represents an aromatic hydrocarbon ring in a form of a single or multiple rings which may have a substitute and which have 6 to 20 carbon atoms; R 1 represents a group other than a hydrogen atom in a form of an aliphatic alkyl group having 1 to 20 carbon atoms, an aliphatic alkoxy group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms or an aralkyloxy group having 7 to 20 carbon atoms, the group containing an atom selected from a carbon atom, an oxygen atom and a nitrogen atom; and R 1 may bond with A to form a ring structure).
