Tandem ring-closing metathesis–radical cyclization based on 4-(phenylseleno)butanal and methyl 3-(phenylseleno)propanoate — a route to bicyclic compounds
Abstract
α,ω-(Phenylseleno) carbonyl compounds, such as 4-(phenylseleno)butanal (1) and methyl 3-(phenylseleno)propanoate (2), are easily converted by anionic reactions into substances that undergo sequential ring-closing metathesis and radical cyclization, affording bicyclic products.
