2-(TRICHLOROACETYL)PYRROLE Chemical Properties,Usage,Production

Uses

2-(Trichloroacetyl)pyrrole, is a building block used for the synthesis of more complex pharmaceutical compounds, such as Oroidin, Hymenidin and Clathrodin.

General Description

2-(Trichloroacetyl)pyrrole is a 2-substituted pyrrole. It undergoes acylation to afford 4-acyl derivatives (4-formyl to 4-hexanoyl).

Synthesis

109-97-7

76-02-8

35302-72-8

To a stirred solution of 2,2,2-trichloroacetyl chloride (25.5 mL, 0.227 mol) in anhydrous ether (45 mL) was added pyrrole (14.3 mL, 0.206 mol) slowly and dropwise at 0°C in an ice bath. The reaction mixture was stirred continuously. After the reaction was carried out for 2 days, brine solution (300 mL) was added to the reaction solution. Subsequently, the mixture was extracted with ethyl acetate (3 x 100 mL) and water (100 mL). The organic extracts were combined, dried with anhydrous magnesium sulfate (MgSO?), and then evaporated to remove the solvent to afford the target product 2,2,2-trichloro-1-(1H-pyrrol-2-yl)ethanone as a brown solid (43.6 g, 99% yield).
