13C NMR Data [δ(13C), 1J(C,H), 1J(C,C)] of some bicycloalkenes

Abstract
The 13C shifts of the bicyclo[3.2.0]alkenes 1‐7, spiro[2.4]hepta‐4,6‐diene (8) and the bicyclo[3.3.0]octenes 9 and 10 have been assigned via one‐ and two‐dimensional INADEQUATE experiments. The values of 1J(C,H) and 1J(C.C) of 1‐10 are also reported.
