Pa. Zoretic et al., AN INTRAMOLECULAR RADICAL APPROACH TO ANGULAR ELECTROPHORES IN POLYCYCLIC SYSTEMS, Tetrahedron letters, 37(11), 1996, pp. 1751-1754
The introduction of an angular C-8 cyano group in polycyclic system 9
has been realized via a stereoselective oxidative radical cyclization
of polyene 8 containing an alpha,beta-unsaturated electrophore.
