Dehydrohalogenation of adducts of dichlorocarbene with cyclooctene and its peripherally cyclopropanated analogs
摘要:
Dehydrohalogenation of three isomeric adducts of dichlorocarbene with bicyclo[6.1.0]non-1-, -2-, and -4-enes under the action of potassium tert-butoxide in DMSO was studied. In the course of dehydrohalogenation of the substrates under study, different isomerization processes, which were accompanied by repeated migrations of multiple bonds that formed, occurred depending on the structure of dichlorides, while no skeletal rearrangements were observed.

Methods for the synthesis of alicyclic derivatives f spiropentane by ]1 +2] cycloaddition of halo- and dihalocarbenes to 1,5-cyclooctadiene followed by dehydrohalogenation and cyclopropanation of the olefins formed are described.
