摘要

Following our success with dienyne 2a, 2a we wished to evaluate the scope of dienyne RCM 5 for the construction of polycarbocyclic systems containing an eight-membered ring. We envisaged that elongation of the alkynyl chain (n = 1) would allow construction of the bicyclo[5.3.1]undecadiene system characteristic of taxanes (Figure 1). 6 The use of hydrindanone 3 as a platform would both aid formation of the eight-membered ring 2 and provide a CD system on which the ...
