  Asymmetric Synthesis of the ABC-Ring System of the Antitumor Antibiotic MPC1001

  摘要：

  trans-4-Hydroxy-L-proline was converted into a tricyclic compound representing three contiguous rings of the anticancer antibiotic MPC1001. The tricyclic model contains the dihydrooxepin and diketopiperazine Subunits, as well as one of the Sulfur atoms of the natural product. The diketopiperazine unit was formed by a new method that involves cyclization of an enolate onto the carbonyl of a phenyl carbamate, and the dihydrooxepin ring was generated by using an acid-induced cyclization of an alcohol onto the beta-carbon of a vinylogous amide.

  An isocyanate production method according to the present invention is a method in which an isocyanate is produced by subjecting a carbamate to thermal decomposition, and includes: a step of preparing a mixture liquid containing the carbamate, an inactive solvent and a polyisocyanate compound; a step of conducting a thermal decomposition reaction of the carbamate by continuously introducing the mixture liquid into a thermal decomposition reactor; a step of collecting a low-boiling decomposition product by continuously extracting the low-boiling decomposition product in a gaseous state from the reactor, the low-boiling decomposition product having a boiling point lower than the polyisocyanate compound; and a step of collecting a high-boiling component by continuously extracting, from the reactor, a liquid phase component which is not collected in a gaseous state at the step of collecting the low-boiling decomposition product.

  根据本发明的一种异氰酸酯生产方法是一种通过将氨基甲酸酯经受热分解而生产异氰酸酯的方法，包括：准备含有氨基甲酸酯、无活性溶剂和多异氰酸酯化合物的混合液的步骤；通过持续将混合液引入热分解反应器对氨基甲酸酯进行热分解反应的步骤；通过持续从反应器中以气态形式提取低沸点分解产物的步骤，所述低沸点分解产物的沸点低于多异氰酸酯化合物；通过从反应器中持续提取未在收集低沸点分解产物的步骤中以气态形式收集的液相组分的步骤来收集高沸点组分。
