Abstract/OtherAbstract:
|
The unprecedented Csp3-Csp3 bond cleavage of the unactivated cyclopentane has been achieved. The RhI-catalyzed cycloaddition of allenylcyclopentane-alkynes produced in situ the 9-cyclopentyl-8-rhodabicyclo[4.3.0]nona-1,6-diene intermediates, which were subsequently susceptible to the [7+2] cycloaddition via β-carbon elimination affording the bicyclo[7.4.0]tridecatriene derivatives in good yields. Changing the RhI catalyst effected the Cγ-H bond activation of the common 9-cyclopentyl-8-rhodabicyclo[4.3.0]nona-1,6-diene intermediate to produce the novel spiro[2.4]heptane skeleton in a site-selective manner. |
