    摘要: The invention is a method for producing δ-aminopentadienoate derivatives of formula (1), the method comprising reacting a streptocyanine derivative of formula (2) with an ester derivative of formula (3) in the presence of an organic base. In formulae (1) to (3), R1 represents an alkyl group or an aryl group; R2, R3, R4 and R5 independently represent a hydrogen atom or an alkyl group; R2 and R3, or R4 and R5 may bond to each other to form a ring; Y represents an electron attractive group; X represents an acid radical; n indicates 0 or a positive number, which is no more than 5; Y may bond to R1 to form a ring
