Participants

Role	Name	HCID	Charge
Reactant	2-Isopropylcyclopentane-1,3-dione	HCID 14382036	—
Reactant	1-(Diethylamino)-6-(3-methoxyphenyl)hexan-3-one	HCID 21485504	—
Product	2-Isopropyl-2-(6-m-methoxyphenyl-3-oxohexyl)cyclopentane-1,3-dione	HCID 21485475	97.7%

Reaction Steps

Condense a mixture (6 g) of 1-diethylamino-6-(m-methoxyphenyl)hexan-3-one and 6-(m-methoxhyphenyl)hex-1-en-3-one with 2-isopropylcyclopentane-1,3-dione (3 g) using a procedure similar to that described for the condensation of the 2-ethyl compound. Obtain the corresponding triketone, 2-isopropyl-2-(6-m-methoxyphenyl-3-oxohexyl)cyclopentane-1,3-dione (7.2 g) as an uncrystallizable gum.
