A radical domino cyclisation reaction of N-cyanamide alkenes, mediated by hydrogen atom transfer (HAT) has been developed. This method, using PhSiH3 and catalytic Fe(acac)3 , allows for the synthesis of challenging (spiro)quinazolinone scaffolds from simple, tractable (hetero)aryl carboxylic acid and cyanamide building blocks.
