3-(1-cyclohexenyl)-, and 3-(1-cycloheptenyl)tropolones (3a, 3b, and 3c) were prepared by the hydrolysis of cycloadducts of dichloroketene to cyclopentylidene-, cyclohexylidene-, and cycloheptylidenecyclopentadiene, respectively. Compound 3a was oxidized with performic acid to give 1,2,3,5-tetrahydrocyclohepta[b]cyclopenta[d]furan-5-one and 3-(2-oxocyclopentyl)tropolone. Oxidation of 3b and 3c gave 1,2,3,4
3-(1-环戊烯基)-、3-(1-环己烯基)-和 3-(1-环庚烯基)托酚酮(3a、3b 和 3c)是通过将二氯乙烯酮的环加合物水解为亚环戊基-、亚环己基- ,和环庚基环戊二烯,分别。化合物3a用过甲酸氧化得到1,2,3,5-四氢环庚[b]环戊并[d]呋喃-5-酮和3-(2-氧代环戊基)托酚酮。3b和3c的氧化得到1,2,3,4-四氢-6H-环庚[b]苯并呋喃-6-酮(4b)和5,7,8,9,10,11-六氢二环庚[b,d]呋喃-5-一个,分别。4b用钯催化剂脱氢得到6H-环庚[b]苯并呋喃-6-酮。
