Sterically Crowded Cyclohexanes, 4. On the Homologation of Hexamethylcyclobutanone: Octamethylcyclopentanone and Decamethylcyclohexanone

Attempts to homologate hexamethylcyclobutanone (5) via oxaspiroalkanes 8 and 9 or, alternatively, via β-hydroxy selenides 10 and 11 are described.An oxaspirohexane-cyclopentanone rearrangement of 8 yielded 6, but the corresponding ring enlargement of 9 fa
