Formation of β-cyano-ketones through cyanide-promoted ring-opening of cyclic organic carbonates
文献信息
Jixiang Ni, Àlex Cristòfol
Here we disclose a method for the unexpected decarboxylative cyanide-assisted ring-opening reaction of a series of vinyl cyclic carbonates. At elevated temperature, the attack of a cyanide nucleophile at the methylenic carbon center of the organic carbonate is promoted which leads to the release of CO2 and MeCN and the intermediacy of a Michael acceptor that undergoes facile 1,4-addition affording a β-cyano ketone product. This chemistry features a rare ring-opening reaction that is not initiated at the typically more electrophilic carbonate carbonyl.
