Catalytic Cycloaddition of 2‑Methyleneaziridines with 1,1-Dicyanoalkenes

Abstract

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
