Abstract Novel restricted diamines, 2-(1-aminocycloalkan-1-yl)ethylamines 1, were prepared by using Michael addition of ethyl cyclohexylideneacetate 2 and cycloalkylideneacetonitriles 7 with amines. In Michael addition, ester 2 needed high reaction temperature and gave several products, whereas 7 reacted smoothly and gave 2-(1-amino-1-cyclohexyl)acetonitriles 8 in good yield (NH3 85%, MeNH2 89% EtNH2

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.
