Abstract

PURPOSE: To prepare the titled substance, by reacting a 3-substituted-5,6-dihydro2(1H)-pyrazinone with a carbonyl compound in the presence of an alkali metal alkoxide, an alkali metal hydroxide, or a quaternary ammonium salt.
CONSTITUTION: A pyrazinone derivative of formula III having various substitutent group at the 5-position is prepared by reacting the compound of formulaI(R1 is alkyl, phenyl, or phenylalkyl) with the compound of formula II (R2 is H or alkyl; R3 is alkyl, aryl, or heterocylic group) in the presence of an alkali metal alkoxide (e.g. sodium methoxide), an alkali metal hyroxide (e.g. potassium hydroxide) or a quaternary ammonium salt (e.g. benzyltrimethylammonium hydroxide) at the refluxing temp.
USE: Synthetic intermediate of perfume, pharmaceutical, and pesticide.
