abstract: |
Regioselective cyclization reactions of 1,3-bis(silyloxy)-1,3-butadienes provide an
elegant approach for the synthesis of various complex carba- and heterocycles. Thus,
various bridged and non-bridged N-heterocycles, functionalized salicylates and pyran-4-ones
are prepared based on cyclization reactions of 1,3-bis(silylenol ethers). Isochromanes
and chromanes are prepared based on chelation-controlled cyclization of 1,3-bis(silylenol
ethers) with 1,1-diacylcyclopropanes. In addition, 6-halomethyl-5,6-dihydro-4H-1,2-oxazines
are synthesized by regioselective cyclization of arylalkenyl-oximes.
