Abstract
PURPOSE: The reaction of 2,3-dihydropyrazine with an aldehyde or ketone is effected in the presence of a base to give title compound useful as a flavor component that is produced when food is baked in only one step in high yeild.
CONSTITUTION: A compound of formula I (R1 and R2 are alkyl, alkenyl) is made to react with an aldehyde such as acetaldehyde, benzaldehyde or ketone such as acetone, cyclohexanone to form a compound of formula II (X and Y are H, alkyl, alkenyl, aryl). An inert solvent such as methanol or benzene is used as a reaction solvent and the reaction temperature is -78W100°C.
USE: Cosmetic perfume, synthetic intermediate of agriculture chemical and medicine.
