- Asymmetric auto-tandem catalysis with a planar-chiral ruthenium complex: Sequential allylic amidation and atom-transfer radical cyclization
-
Ru does it all: A novel example of an asymmetric auto-tandem reaction catalyzed by a planar-chiral cyclopentadienyl-ruthenium complex is described. The reaction of allylic chloride with α-haloamides provides synthetically useful, diastereomerically and enantiomerically enriched γ-lactams with multiple stereogenic centers through one-pot sequential allylic amidation/atom-transfer radical cyclization.
