2,4-Piperadinedione Chemical Properties,Usage,Production
Description
2,4-Piperidinedione is an important piperidine ring-containing intermediate, and its 2,4-piperidinedione, as a characteristic fragment, is widely used as an intermediate in the synthesis of ibrutinib and paliperidone drugs.
Chemical Properties
White to light yellow solid
Uses
2,4-Piperidinedione is a reactant in the synthesis of 1,4-dihydropyridines as TGFβ/Smad inhibitors.
Preparation
The synthesis of 2,4-Piperidinedione involved dissolving 400 mg (2.34 mmol, 1.00 eq.) of Methyl 2,4-dioxo-piperidine-3-carboxylate in a mixture of acetonitrile (20 mL) and water (0.2 mL). The solution was then heated to approximately 86° C. and maintained at this temperature for around 4 hours. After completion of the reaction, the solvent was removed under vacuum, leaving behind a residue of 2,4-Piperidinedione. This residue was further purified using silica gel column chromatography with a mobile phase consisting of dichloromethane and methanol in a ratio of 100:1. The target product, 2,4-Piperidinedione, was obtained as a white solid, with a yield of 27%, corresponding to 70 mg.
Synthesis
845267-78-9
50607-30-2
The general procedure for the synthesis of 2,4-piperidinediones from tert-butyl 2,4-dipiperidone-1-carboxylate was as follows: at 0 °C and under nitrogen protection, Boc-β-alanine (25 g, 132 mmol), Meldrum acid (20.9 g, 145 mmol), and 4-dimethylaminopyridine (DMAP, 24.2 g, 198 mmol) were dissolved in 700 mL of anhydrous dichloromethane (DCM). To this solution was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCI, 30.4 g, 158 mmol). The reaction mixture was slowly warmed to room temperature and stirred overnight. After completion of the reaction, the reaction mixture was washed with 5% KHSO4 aqueous solution (0.5 L x 4). The organic layer was dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give the crude product [tert-butyl [3-(2,2-dimethyl-4,6-dioxo-[1,3]dioxol-5-yl)-3-oxo-propyl]-carbamate. The crude product was dissolved in 600 mL of ethyl acetate and refluxed for 4 hours. It was concentrated under reduced pressure to a volume of about 150 mL and subsequently crystallized at 4°C overnight. The solid was collected by filtration and washed with cold ethyl acetate to afford 18.4 g (65% yield) of 2,4-piperidinedione.1H NMR (400 MHz, DMSO-D6) δppm: 1.44 (s, 9H), 2.44 (m, 2H), 3.71 (m, 2H), 4.95 (s, 1H), 11.2 (bs, 1H). The resulting product was converted quantitatively to piperidine-2,4-dione by dissolving in dichloromethane and treating with trifluoroacetic acid for 3 h at room temperature.
