Primary 1-Arylcyclopropylamines from Aryl Cyanides with Diethylzinc and Titanium Alkoxides
摘要:
[GRAPHICS]1-Aryl-substituted primary cyclopropylamines are conveniently prepared from aromatic nitriles and diethylzinc. The yields range from 40 to 56% for donor-substituted (five examples) to 62-82% for non- and acceptor-substituted substrates (nine examples).

The reaction of various aromatic nitriles with 1.1 equiv of Ti(Oi-Pr)(4) and 2.2 equiv of EtMgBr followed by addition of a Lewis acid gave 1-aryl cyclopropylamines in 43-76% yields. Under similar conditions, conjugated alkenenitriles afford 1-alkenylcyclopropylamines (42-65%).

to high enantioselectivity relies on two distinct ligands that act cooperatively: an exogenous monodentate chiral phosphite that induces enantioselectivity and an endogenous acetylacetonate that exerts a remarkably positive influence on the enhancement of enantioselectivity. Detailed experimental and computational studies elucidate the effect of ligand cooperativity and the key steps involving σ-bond
