✦ Synopsis

We wieh to report photochemical cleavage of a bioyclic ketone V yielding cyclopentadecanone (Exaltone) (VIII) or its precursor IX. The ketone V has been obtained from cyolododecanone (II) (l), hence this constitutes the first practical preparation of VIII from 1,5,+oyclododeoatriene (I), a readily available cyclotrimer of butadiene (2).
