标 题 :Novel process for synthesis of polysubstituted pyridine derivatives

摘要:The present invention relates to a novel method for synthesizing a polysubstituted pyridine derivative and, more specifically, to a method for synthesizing a 2,3,5-substituted pyridine derivative through a specific ring cleavage reaction. In the synthesis method of the present invention, an enamine structure is formed in situ by using beta keto ester/sulfone/phosphonic acid ester and ammonium acetate and subjected to an aldol condensation reaction with 3-formyl (aza) indole/benzofuran, a cyclization reaction, and a ring-cleavage reaction in that order to synthesize a characteristic pyridine structure having an alkyl/aryl substituent attached to the 2-position thereof, an ester/sulfone/phosphonic acid ester attached to the 3-position thereof, and ortho-aminoaryl/phenol including various substituents attached to the 5-position thereof. In particular, (aza)indole/benzofuran and beta keto ester/sulfone/phosphonic acid ester, which are reaction substrates, are substrates having very high accessibility, and enable the introduction of various substituents, thereby constructing a pyridine skeleton having high biocompatibility into which ortho-aminoaryl or phenol substituents having various substituents are introduced.
