    • This invention relates to an improved process for the preparation of 5-methylchroman-6-carboxylic acid, a useful intermediate in the preparation of chroman-containing diacylhydrazines which are useful as insecticides, by reacting a Hagemann's ester with a propargyl derivative in the presence of a base and a solvent to produce a propargyl ether, rearranging the propargyl ether by application of heat with a suitable catalyst being present, with or without a solvent, to produce a cyclic ether type compound and isomerizing the cyclic ether type compound with a catalyst in a suitable solvent to produce a chroman ester. The propargyl ethers and the cyclic ether type compounds produced by the process of the present invention are new.

    • The apparatus and method of the present invention provides for conducting simultaneous multiple synthesis of general compounds, which often takes place under varied uneven conditions requiring heating, cooling, agitation, reagent/solvent additions to the reactor contents at each reaction vessel location, supply and maintenance of inert atmosphere and means to facilitate the reflux of the reactor contents. Thus, it becomes necessary to monitor and control the reaction conditions during the simultaneous multiple synthesis of general compounds. The apparatus allows the user to connect various independently controlling and conveying means to each reaction vessel through multiple ports provided on a stopper mounted on each reaction vessel. The apparatus of the present invention permits user to readily access the reaction vessels without interrupting the reactions occurring in the adjacent reaction vessels. The unique geometry and shape of the stopper allows positioning of multiple ports, while still providing the stopper with a compact size. As a result, a large array of reaction vessels can be accommodated in the device of the present invention without significantly increasing the overall size of the apparatus. Some of the general compounds that can be readily synthesized by the apparatus and the method of the present invention include inorganic compounds as well as organic compounds, such as oligomers, polymers, agricultural chemicals, drugs, peptides and oligonucleotides.
    • 本发明的装置和方法提供了一般化合物的同时多重合成,这些化合物通常发生在需要加热,冷却,搅拌,每个反应容器位置的反应器内容物的试剂/溶剂添加的不同不均匀条件下,供应和维护 的惰性气氛和促进反应器内容物回流的手段。 因此,需要在通用化合物的同时多重合成中监测和控制反应条件。 该装置允许用户通过设置在安装在每个反应容器上的止动件上的多个端口将各种独立控制和输送装置连接到每个反应容器。 本发明的装置允许用户容易地进入反应容器而不中断相邻反应容器中发生的反应。 止动器的独特几何形状和形状允许定位多个端口,同时仍然为塞子提供紧凑的尺寸。 结果,可以在本发明的装置中容纳大量反应容器,而不会显着增加装置的总体尺寸。 可以通过本发明的装置和方法容易地合成的一些一般化合物包括无机化合物以及有机化合物,例如低聚物,聚合物,农药,药物,肽和寡核苷酸。
