Abstract: | New conjunctive β‐silylated organometallic reagents of Li, Mg, and Zn have been prepared and used for an expeditive construction of various polyfunctionalized 5‐, 6‐, and 7‐membered heterocycles, such as furans, pyrroles, quinolines, benzo[b]thieno‐[2,3‐b]pyridine, naphthyridines, fused pyrazoles, and 2,3‐dihydro‐benzo[c]azepines. The latent silyl group has been converted into various carbon–carbon bonds in most heterocycle types. |
