The potential use of 1-trimethylsilyloxybicyclo[n.l.O]alkanes, 2, 1 as useful synthetic intermediates has recently been demonstrated. Not only do A serve as precursors to the corresponding cyclopropanols, ,2, 2 but treatment of ,& with acid,3 base,4 or halogen5 results in the
Novel cyclopropane-shift type reaction of diaryl(2-halogenocyclopropyl)methanols 2b and 7 proceeded by using BF 3 . OEt 2 and TiCl 4 , respectively. Utilizing these reactions, 1-aryl-3-chloro-1,2-methanoindans 5 and 9, 1-aryl-3-methylnaphthalenes 6, and 1,2-methano-1-arylindens 10 were constructed.
Suzuki cross-coupling reactions between a variety of iodocyclopropanes and cyclopropylboronate esters to produce symmetrical or unsymmetrical contiguous cyclopropanes was achieved in good yields.
