Novel routes to benzofurans using titanium-alkylidene chemistry
The first route looked at the alkylidenation of esters i to give -alkoxyvinylstannanes ii. A cross-coupling reaction would have given enol ester products iii, followed by an acid-induced cyclisation to give the desired benzofurans iv. (Fig. 13510A) The approach was not successful, but during the cou...
