摘要:The invention relates to a new enantioselective synthesis for the preparation of optically active 14-oxo-E-homo-eburnane derivatives of the formula (Ia) ##STR1## wherein R 1 is alkyl having from 1 to 4 carbon atom. In the synthesis optically active 6-alkoxycarbonylhexahydroindoloquinolizinium salts are employed as starting materials, which contain a center of chirality at the site of attachment of the carboxyl group. This center of chirality preserves the optical activity of the optically active tryptophan ester from which this compound has been prepared until a new center of chirality is formed in the molecule in a configuration corresponding to the desired end product. The carboxyl group, which is not needed in the end product and only serves to preserving the optical activity can then be eliminated. n Compounds of the formula (Ia) are known in the art and may be used in the synthesis of (+)-vincamine and (+)-apovincaminic acid ethylester.

摘要:Disclosed is a method for the continuous synthesis of 4-ethoxy-1,1,1-trifluoro-3-buten-2-one. The continuous synthesis method comprises: continuously introducing a raw material comprising vinyl ethyl ether, triethylamine and trifluoroacetic anhydride into a continuous reactor for a reaction to obtain a product system containing 4-ethoxy-1,1,1-trifluoro-3-buten-2-one, and continuously extracting the product system to obtain 4-ethoxy-1,1,1-trifluoro-3-buten-2-one. By using the continuous process, the above-mentioned raw materials can all be conveniently and accurately introduced into the continuous reactor, and after the reaction is completed, continuous extraction is also used for a post-treatment. The whole process is rapid, simple and efficient, the efficiency of the whole synthesis process is greatly increased, product destruction loss is reduced, and hidden safety hazards during batch production are avoided. After scaling up, there is no amplification effect, and safety and a relatively high synthesis efficiency can still be maintained.

摘要:The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

摘要:This invention describes various processes for synthesis and resolution of racemic amino-substituted fused bicyclic ring systems. One process utilizes selective hydrogenation of an amino-substituted fused bicyclic aromatic ring system. An alternative process prepares the racemic amino-substituted fused bicyclic ring system via nitrosation. In addition, the present invention describes the enzymatic resolution of a racemic mixture to produce the (R)- and (S)-forms of amino-substituted fused bicyclic rings as well as a racemization process to recycle the unpreferred enantioner. Further provided by this invention is an asymmetric synthesis of the (R)- or (S)-enantiomer of primary amino-substituted fused bicyclic ring systems.

摘要:Methods for the synthesis of lactams are presented whereby a carboxylic acid of the formula HOOC—OR—NH-LG, wherein OR is an organic moiety and LG is a leaving group, is reacted with an acid, such as an organic acid, in particular a strong acid, and a dehydrating agent, which may be one in the same such as a strong acid anhydride, such that the amount of acid added allows for the desired transformation to take place without the loss of the leaving group (LG) before the cyclization, and recovering the lactam.
