An Efficient Preparation of 2H-Cyclohepta[b]furan-2-ones
摘要:
2H-cyclohepta[b]furan-2-one (3) was prepared in high yield from a [2+2] cycloadduct between cycloheptatriene and dichloroketene by Baeyer-Villiger oxidation followed by dehydrochlorination. 3-Chloro- (8) and 6-chloro-2H-cyclohepta[b] furan-2-one (9) were obtained from the [2+2] cycloadduct by adding an epoxidation step to the above synthetic way in moderate yields.
