Abstract:
1. A process for producing a δ-aminopentadienoate compound represented by the following formula (I), the process comprising reacting a δ-aminopentadienoate compound represented by the following formula (II) with an alcohol represented by the following formula (III): wherein in formulae (I) to (III), R 11 and R 21 each independently represent an aliphatic group, an aromatic group, or a heterocyclic group bonded via a carbon atom; R 12 , R 13 , R 14 , R 15 and R 16 each independently represent a hydrogen atom, an aliphatic group, an aromatic group, or a heterocyclic group bonded via a carbon atom; Y 11 represents an electron-withdrawing group whose Hammett's substituent constant σ p value is a positive numerical value; R 12 and R 13 may be bonded to each other to form a ring; R 13 and R 15 may be bonded to each other to form a ring; R 15 and Y 11 may be bonded to each other to form a ring; Y 11 and R 11 may be bonded to each other to form a ring; Y 11 and R 21 may be bonded to each other to form a ring; R 11 and R 14 may be bonded to each other to form a ring; R 21 and R 14 may be bonded to each other to form a ring; R 14 and R 16 may be bonded to each other to form a ring; R 16 and R 12 may be bonded to each other to form a ring; and R 11 and R 21 are not the same group.
