variously substituted derivatives of 1. Diols 38 failed to give any detectable amount of IMDA type ringclosure, leading only to dialdehyde 39. For the compounds studied, alkyl or carboxyalkyl substituents on the olefin 41 and 44 led to incomplete cascade transformation due to steric interference caused by the alkyl or acyl groups. The oxidative cleavage of unsaturated diols 46 and 48 derived from monocyclic
