Catalytic cycloaddition of 2-methyleneaziridines with 1,1-dicyanoalkenes.
2-Methyleneaziridine are a good substrate for the catalytic synthesis of cyclopentylidenamines via a [3 + 2] cycloaddition of 1,1-dicyanoalkenes using Bu2SnI2 as an effective catalyst. A C-attack from 2-methyleneaziridine yielded the desired products.
