Negishi, Ei-ichi published the artcileA Novel, Highly Selective, and General Methodology for the Synthesis of 1,5-Diene-Containing Oligoisoprenoids of All Possible Geometrical Combinations Exemplified by an Iterative and Convergent Synthesis of Coenzyme Q10, Recommanded Product: (4-Bromobut-1-yn-1-yl)trimethylsilane, the publication is Organic Letters (2002), 4(2), 261-264, database is CAplus and MEDLINE.
A truly general, versatile, and highly regio- and stereoselective methodol. for the synthesis of terpenoids containing 1,5-diene units of E and/or Z geometry critically involves Pd-catalyzed homoallyl- and homopropargyl-alkenyl coupling and Zr-catalyzed carboalumination of alkynes. By using this methodol., coenzyme Q10 (I), (E,Z,E)-geranylgeraniol (II), and other natural or unnatural compounds have been synthesized efficiently.
