摘要

1, I-Dihalocyclopropanes have been prepared from enol ethers derived from cyclohexanone, cycloheptanone, and cyclooctanone. The product derived from cyclohexanone afjords I-ethoxy-1, 3, 5-cycloheptatriene (5) in 55% over-all yield by a two- step process involving pyridine with subsequent reaction of the intermediate chlorodiene 4 with potassium t-butoxide, or in 37z yield by a onestep-process involving quinoline. ...
