RING OPENING AND RING ENLARGEMENT OF A CYCLOPROPENE CARBOXYLIC ACID

3,3-Dimethyl-2-phenyl-cyclopropenecarboxylic acid 4 is prepared, starting with chlorophenyldiazirine 1.With acids 4 yields the open chain carboxylic acids 5, 6 and 7.Thionylchloride leads to the cyclobutenone 10, DCC to the acid anhydrides 11 and 13.

Cycloaddition Reactions of Strained Ring Systems. Photosensitized Cycloadditions of 2-(Acyloxy)-Substituted Cyclopropenes

The sensitized photocycloaddition reaction of 1-phenyl-2-carbomethoxy-3,3-dimethylcyclopropene with a series of phenyl-substituted olefins has been investigated.The photocycloaddition is sensitive to steric factors with the reactants approaching eac
