ChemInform Abstract: A Donor—Acceptor Cyclopropene as a Dipole Source for a Silver(I) Catalyzed Asymmetric Catalytic [3 + 3]‐Cycloaddition with Nitrones. Issue 9 (4th March 2014) - Xu, Xinfang
Abstract Ag(I)‐catalyzed asymmetric formal [3 + 3]‐cycloaddition of nitrones (III) to the donor‐acceptor substituted cyclopropene (II) affords 3, 6‐dihydro‐1, 2‐oxazine derivatives (IV) (19 examples) in high yields with exceptional stereocontrol.
