rearrangement which proceeds by way of a strained cyclic allene intermediates (e.g.,17). This leads to the formation of angularly fused triquinanes (e.g., 20) in which each of the rings is functionally differentiated. Bicyclo[6.3. 0]undecadienones (e.g., 36) are the major products when the reactions are quenched with aqueous bicarbonate rather than TBAF. Under analogous conditions 2-alkylidene-1-alkynylbicyclo[3

2,3,4-Trisubstituted 4-hydroxy-2-cyclobutenones, prepared by regiospecific synthesis of substituted cyclobutenediones, undergo Lewis acid facilitated ionization to cyclobutenyl cations, which are trapped by trialkylsilanes in a regioselective sense. Thermolysis of the resulting cyclobutenones affords phenols in high yields.
