General description

Allyl 1H-imidazole-1-carboxylate is an organic reagent used to introduce carboxyallyl groups to nucleophilic nitrogen, oxygen, and carbon centers. It is used in the acylation reactions of enolates and nitrogen compounds. Further, it can also be used in the synthesis of carbonates and allyl esters.

Application

Allyl 1H-imidazole-1-carboxylate can be used:
  • To prepare allyl enol carbonate derivatives by reacting with ketone enolates and boron trifluoride etherate.
  • In the acylation of a mixture of primary and secondary alcohols.

Heller Group – Professor Product Portal

Professor Heller and coworkers are engaged in the development of mild and chemoselective acylation reactions using carbonylazole-derived reagents. To that end, they have developed a suite of carbonylimidazole derivatives for facile and chemoselective esterification (MImC, etc.) and amidation (WImC) of carboxylic acids, in collaboration with Professor Richmond Sarpong.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
