Ethyl isocyanoacetate Chemical Properties,Uses,Production

Chemical Properties

Light yellow to brom liquid

Uses

Ethyl isocyanoacetate can be used to prepare pyrroles,1,2 oxazolines, benzodiazepines, oxazoles and imidazoles.

Preparation

synthesis of ethyl isocyanoacetate
A solution containing N-formyl glycine ethyl ester (1, 1.31 g, 10 mmol), DIPEA (2.62 g, 20 mmol) and DMAP (0.45 g, 3 mmol) in dry DCM (10 mL) was loaded in a sample loop and combined with a second stream containing triphosgene (2, 0.98 g, 3.3 mmol) also dissolved in dry DCM (10 mL) at individual channel flow rates of 0.5 mL/min. The combined stream was directed into two linked 10 mL FEP reactor vessels to achieve a 20 minutes residence time at ambient temperature. The output was collect and the solvent was carefully evaporated to 80% of its total volume. The crude material was filtered through silica (5 g) and washed with DCM (2 × 10 mL) to obtain the salt-free product. The desired product 3 was obtained as dark yellow oil after evaporation of the organic phase (1.03 g, 91 % isolated yield, >97% purity by 1H NMR).
