Outline of Final Research Achievements |
Synthesis of solanoeclepin A, the most active hatching agent of potato cyst nematode isolated from hydroponic potato cultures was examined not only for the chemical supply of solanoeclepin A but also for the structure-activity relationship study. As a result, we have demonstrated the power of 4-exo-trig radical cyclization for construction of the highly strained cyclobutane found in solanoeclepin A. Since the substrate is readily prepared from Hajos-Parrish ketone, samarium(II)-mediated 4-exo-trig radical cyclization could provide one of the most straightforward accessible routes to the tricyclo[5.2.1.01,6]decane skeleton of solanoeclepin A.
