compounds undergo acid-catalysed 1,2-cyclopropane (santolinyl) scission; on the other hand, 2,2-dimethyl-3-(2-methylpropenyl)-cyclopropylmethanol (chrysanthemyl alcohol) and various similar compounds undergo 1,3-(artemisyl) cleavage. Introduction of functional groups into the methylpropenyl side-chain in chrysanthemic-type structures allows acid-catalysedcleavage by a 2,3-(lavandulyl) pathway. Certain
