Article abstract of DOI:10.1021/jo00133a035

Compounds 11c, 12, and 13 have been synthesized as potential precursors for the 2-substituted bicyclo<3.3.1>non-1(2)-en-3-ones 5 (R = Ph and t-Bu).The lactone 34 and its derivatives 32 have also been synthesized as potential precursors for the parent bicyclo<3.3.1> enone 1.
