摘要：

Starting from Ethyl-malealdehydicacid pseudoester (5) 4(2-Methylpropenyl)cyclobutane-1-carboxylic acids 2, 3 and 4 were synthesized via a photosensitised (2 + 2)-cycloaddition with 2,3-dimethylbutene-2 resp. isobutene as a partner. The cycloadducts lead to the corresponding aldehydecarboxylic acids resp. their pseudoacids, which subsequently in a Wittig-reaction are converted to the isobutenyl-cyclobutane-carboxylic acid derivatives 2, 3 and 4. These acids as cyclobutane-analoges to naturally occurring Chrysanthemumic-acid are investigated. © 1979.
