摘要

The products resulting from the interaction of cyclopentanone, cyclohexanone, cycloheptanone and acetone with one or more of the bis-diazoalkanes derived in situ from bis-nitrosourethans of the structure [X (XO)(CO, E~)] Z (CH~), where 7t is 3, 4, 5 and 6 have been investigated. In several instances, bridged ring ketones are produced, leading to syntheses of 8-ketobicyclo [5, 1, 1 jnonane, 9-ketobicyclo [4, 2, 1 Inonane and 10- ...
