Abstract

The reactions of propellanes containing one or two cyclohexadiene rings with singlet oxygen take the course of exclusive syn-attack with respect to a hetero-ring containing two CO groups. When only one or no CO group is found in the hetero-ring, both syn-and anti- attack occur. The former course is interpreted in terms of secondary orbital interactions which stabilize the transition state for syn-attack.
