Abstract: PROBLEM TO BE SOLVED: To provide a new process for the continuous preparation of a 5- alkoxy-substituted oxazole in high yield and high space-time yield. SOLUTION: The process for the continuous preparation of a 5-alkoxy- substituted oxazole of formula I (R 1 is a substituted or unsubstituted 1-6C alkyl; and R 2 is H or a substituted or unsubstituted 1-6C alkyl) comprises the conversion of a continuously charged α-isocyanoalkanoic acid ester of formula II to the 5-alkoxy-substituted oxazole of formula I in a reactor at ≥80°C in the presence of an assistant selected from continuously charged alcohols and esters and the continuous discharge of the reaction product from the reactor.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a 5-alkoxy-substituted oxazole and a method for producing a pyridoxine derivative. SOLUTION: The 5-alkoxy-substituted oxazole is obtained by converting an α-isocyano alkylic acid ester in the presence of a base at >80°C and separating the 5-alkoxy-substituted oxazole from the reaction mixture simultaneously with the converting reaction, and the pyridoxine derivative is obtained by converting an amino acid into an amino acid ester, converting the obtained into a formamido acid ester, converting the obtained into an α-isocyanoalkyl acid ester, converting the obtained into a 5-alkoxy-substituted oxazole in the presence of a base at >80°C and separating the 5-alkoxy-substituted oxazole from the reaction mixture simultaneously with the converting reaction, reacting the obtained 5-alkoxy-substituted oxazole with a protective diol to obtain an Diels-Alder adduct and treating the obtained with an acid and removing the protective group to convert into the pyridoxine derivative.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject alkyne diol by allowing a specific compound to react with acetylene in the presence of a basic alkali metal salt as a catalyst in a polar aprotic solvent in need of a trace or catalytic amount of base. SOLUTION: (A) A compound of the formula: R1-C(=O)-R2 [R1 and R2 are each H, a 1-20C hydrocarbon (which may bear a C-C double or triple bond that is interrupted with a substituted and nonadjacent hetero atom)] and (B) acetylene are allowed to react with each other in the presence of (C) a catalyst of a basic alkali metal salt in an amount of 5-65 mol.% based on the component B in (D) a polar aprotic solvent (for example, tetrahydrofuran) under a pressure of 0.1-10 bar at -20-60 deg.C to give an objective compound represented by the formula: R1R2C(OH)-C≡C-C(OH)R1R2. As the component C, is preferably cited an alkali metal alkoxide (for example, potassium alkoxide).

Abstract: PROBLEM TO BE SOLVED: To provide a distillation column having high separation efficiency, in which the vapor amount is made constant all over the column including a feed section and a side steam take-off section.
SOLUTION: Partition walls DW are arranged substantially along the longitudinal direction of the distillation column so that the inside of the distillation column is divided into an upper zone 2 and a lower zone 4 of the feed section, an upper zone 3 and a lower zone 5 of the side stream take-off section, an upper common column section 1 and a lower common column section 6. A feeding mixture to be separated between the zones 2 and 4 of the feed section is in a wholly or partially vaporized state and/or the side stream to be taken off from the zones 3 and 5 of the side stream take-off section is in a wholly or partially vaporized state.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a 5-alkoxy-substituted oxazole, especially a 4-methyl-5-alkoxy-substituted oxazole and further a method for producing a pyridoxine derivative. SOLUTION: The method for producing the substituted oxazole is carried out as follows. An α-isocyanoalkanoic acid ester is converted into the 5-alkoxy- substituted oxazole in the presence of an assistant composed of an alcohol or an ester at >80°C. The resultant 5-alkoxy-substituted oxazole is taken out of the reactional mixture simultaneously with the conversion. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a method for continuously producing a 5-alkoxy-substituted oxazole and a method for producing a pyridoxine derivative by using the same. SOLUTION: This method for obtaining a pyridoxine derivative is provided by converting an α-isocyanoalkanoic acid ester expressed by the formula II in the presence of continuously supplied base at ≥80°C temperature to a 5- alkoxy-substituted oxazole I, taking it out from a reactor at the same time with the reaction, performing a reaction of the compound I with a compound VI to make a compound VII, and acid-treating it to obtain a pyridoxine derivative IX (in formulae, R 1 is an alkyl, R 2 is H or an alkyl, R 3 , R 4 are each independently a protection group of hydroxy group).
