Formal Asymmetric Cycloaddition of Activated α,β-Unsaturated Ketones with α‑Diazomethylphosphonate Mediated by a Chiral Silver SPINOL Phosphate Catalyst

An efficient method for preparing highly functionalized chiral nonspiro-phosphonyl­pyrazolines via an asymmetric formal 1,3-dipolar cycloaddition reaction of α-diazomethyl­phosphonate with activated, acyclic α,β-unsaturated ketones, bearing an additional nitrile electron-withdrawing group, has been...
