摘要

The reactive bicyclo [nlO] alk-l (w)-enes (n= 3-6) 9a-d are formed by dehydrochlorination of 8a-d and trapped by diphenylisobenzofuran as exo Diels-Alder adducts 1Oa-d. With 8c the major adduct, 18 results not from interception of 9c but from diene 16 that is formed by dehydrochlorination/rearrangement sequences. Attempted interception of cyclopropenea 9a- d by furan provides a [4+ 21 product 19 from 9b (n= 4) only. Under the conditions ...
