The stereochemistries of cycloadditions of mesitonitrile oxide to norbomadiene and nine 7-substituted derivatives have been investigated. The stereoselectivities are controlled primarily by torsional effects which are altered by 7-substituents.

The isomerization of norbornadiene to cycloheptatriene takes place under relatively severe thermal conditions (425");3 however 7-alkoxy or 7-phenyl substituted norbornadienes undergo a more facile (170") thermal rearrangement to the corresponding tropyl derivative. 4 A similar reaction involving con

Nechanistic aspects of thermal sigmatropic rearrangements in cycloheptatrienes have been studied extensively.2 In contrast, the synthetic potential of these isomerization reactions has been exploited only recently.
