    • Several attempts were made to develop a more convenient procedure involving fewer steps for obtaining 34. For example, the dialdehyde compound derived from 26 (e.g., compound 6 in Scheme 1) was reacted with dicerium acetylide or diiodoacetylene derivatives, prepared from 13, to afford an intractable mixture.

    • note
    • Several preliminary attempts on conversion of 35 into the corresponding bicyclo[7.3.0]dodecadiyne derivatives were made under typical aldol conditions by using LDA or LHMDS. However, no ring closed compounds have so far been isolated from the reaction mixture.
