| titleOfInvention | Method for producing pyridine derivatives |
| abstract | Formula 3n n n [Formula 3]n n n n n n n n Wherein A represents a divalent organic group which may contain from 1 to 3 oxygen atoms, nitrogen atoms and / or sulfur atoms, and A represents 5-, 6-, 7-, or 8 together with the two bonded carbon atoms -Can form a membered ring, said ring can form a condensed ring having one or more additional rings; R 5 is a hydrogen atom, -CHR 1 R 2 , or a substituted alkenyl group, aryl group or aral R 1 and R 2 each independently represent a hydrogen atom or a substituted hydrocarbon group; R 6 represents a hydrogen atom, a substituted alkyl group, an alkenyl group, an aryl group, or an aralkyl group. Pyridine alcohol derivatives are represented by Formula 1a.n n n [Formula 1a]n n n n n n n n A pyridine ester derivative represented by (wherein Z 1 represents -COX; X represents an alkoxyl, alkenyloxy, aryloxy or aralkyloxy group which may be substituted; A is as described above). , By reacting with an alkylating agent, alkenylating agent, arylating agent or aralkylating agentn n n [Formula 2]n n n n n n n n Obtaining a pyridine carbonyl derivative represented by (where A and R 5 are the same as above); The resulting pyridine carbonyl derivative is prepared by reacting with a reducing agent, alkylating agent, alkenylating agent, arylating agent or aralkylating agent. |
