Starting from the γ-lactone cis-1, two new syntheses of γ-damascone ((E)-4) are described.In both syntheses, the key step involves the β-cleavage of a bis(homoallylic)potassium alkoxide, viz. the transformation of 3a to 20 and (E/Z)-4, and the conversion

On singlet excitation (λ=254 nm) in MeCN the hydroxy-epoxydiene (E)-4 undergoes photocleavage to the carbene intermediates d and e as main processes.The carbene d, showing behaviour typical of vinyl carbenes, undergoes addition to the adjacent double bond
