title: Six-membered cyclic nitronates as 1,3-dipoles in formal [3 + 3]-cycloaddition with donor-acceptor cyclopropanes. Synthesis of new type of bicyclic nitrosoacetals.
abstract: The first formal [3 + 3]-cycloaddition of nitronates with donor-acceptor cyclopropanes is reported. The reaction is catalyzed by ytterbium trifluoromethanesulfonate and leads to hitherto unknown bicyclic nitrosoacetals, possessing two annelated six-membered rings.
