7, 7-Dimethyltricyclo[3.3.0.0.2, 8]octan-3-ones as Synthetic Intermediates. I. : Preparation and Cyclopropane Ring Opening of 7, 7-Dimethyl-5-(2-propenyl)tricyclo[3.3.0.02, 8]octan-3-one

7, 7-Dimethyl-5-(2-propenyl)tricyclo[3.3.0.02, 8]octan-3-one (4) was prepared from 4, 4-di-methyl-2-cyclopentenone in several steps. The Birch reduction of 4 resulted in exclusive formation of a bicyclo[3.3.0]octanone (14)through C2-C8 bond clevage, while its substitutional reactions yielded bicyclo...
