| Abstract: | 2-substituted cyclopentanone 4 was prepared via the addition-rearrangment processbetween 2-chloro-cyclopentanone and a Grignard reagent. After bromination and dehydrobro-mination of 4, 2-substituted cyclopentenone 5 resulted. Methyl 3-oxo-2-substituted cyclopent-yl acetate was obtained by the addition of methyl sislyl acetate to cyclopentenone 5. followedby removal of the sislyl group with potassium flouride. |
