DM Chem. Reu. 1979, 79, 491. as its a-methyl derivative at C-1 (entry 4), efficiently gave a single new compound under the reaction conditions. In choosing 2, it was anticipated that simple exposure of 3 to a Lewis acid (LA) should, following workup, effect cleavage, 12 due to the strong stabilizing nature of the functional groups located on the incipient carbocation (ie, 4). Quenching with soluble hydroxide ion (see Experimental Section) should return the ...
