Gl. Lange et al., SYNTHESIS OF THE SESQUITERPENOID TRICHODIENE USING A FREE-RADICAL FRAGMENTATION APPROACH, Tetrahedron letters, 39(31), 1998, pp. 5489-5492
A highly regio- and stereoselective synthesis of the sesquiterpenoid t
richodiene is reported. The approach requires only nine steps starting
with a [2+2] photoaddition and employs the free radical fragmentation
of an ''external'' cyclobutane bond in a key step. (C) 1998 Elsevier
