摘要：

Oxidative free-radical cyclization of the unsaturated beta-keto imide 3 containing Oppolzer's D-camphor sultam as a chiral auxiliary was studied. Intramolecularly promoted oxidative free-radical cyclization of 3 with Mn (III) in the presence of Cu (II) produced the stereoisomeric cis-hydrindanones 4 and 5 in a 3:1 ratio at 25-degrees-C.
